Answer:
Hey!
The area would be 13.85Step-by-step explanation:-
Area of a circle's equation is π[tex]r^{2}[/tex] (pi [tex]r^{2}[/tex])
Since the radius is 2.1 and value of pi is 3.14cm,
area is
[tex]2.1^{2}[/tex] x 3.14
4.41 x 3.14
= 13.85
The area of this circle is 13.6.
What is the area of the circle?Area of a circle is the region occupied by the circle in a two-dimensional plane.
The area of the circle is;
[tex]\rm Area \ of \ circle=\pi r^2\\\\Where\ r =radius[/tex]
The radius is 2.1.
Substitute all the values in the formula
[tex]\rm Area \ of \ circle=\pi r^2\\\\ Area \ of \ circle=3.14 \times 2.1^2\\\\ Area \ of \ circle=13.6[/tex]
Hence, the area of this circle is 13.6.

Can someone please help me with this question the instructions are to use a calculator to find the perimeter (the solid lines and curves) of each figure. The perimeter of each semicircle can be found by using the equation 1/2 pi d (the place where I put the words pi has the pi symbol, and d is just a variable. Also use 3.14 as pi, and the top part is cut off a little bit, but it still counts as a full semi circle. Please help me.
Answer:
The continuous closed line that makes the boundary of a two-dimensional shape is known as the perimeter. It’s easy to work out the perimeter of a shape with straight edges, such as a square, because you simply add the lengths of each edge together. A different formula is required to work out the perimeter of a semi circle (a circle cut in half), because it consists of a curved edge as well as a straight edge. That formula is
Step-by-step explanation:
P = \frac{1}{2} πd + dP=

1
πd+d
where d is the diameter of the semi circle.
Apply the number pi (π) to the formula
P = \frac{1}{2} πd + dP=

πd+d
Pi is a circle's circumference divided by its diameter and is always the same value, 3.14.

A single die is rolled. Find the probability of rolling 2 or an odd number.
Answer:
4/6 or 2/3
Step-by-step explanation:
1/2 of the die is odd numbers so, you would add one more number which would be 4/6 or 2/3
The probability of rolling 2 or an odd number is 2/3.
What is probability?"Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one".
For the given situation,
Rolling a die s = {1,2,3,4,5,6}
⇒[tex]n(s)=6[/tex]
The event a is rolling 2 = {2}
⇒[tex]n(a)=1[/tex]
Probability of rolling 2, [tex]p(a)=\frac{n(a)}{n(s)}[/tex]
⇒[tex]p(a)=\frac{1}{6}[/tex]
The event b is rolling an odd number = {1,3,5}
[tex]n(b)=3[/tex]
Probability of rolling an odd number, [tex]p(b)= \frac{n(b)}{n(s)}[/tex]
⇒[tex]p(b)=\frac{3}{6}[/tex]
Thus probability of rolling 2 or an odd number = [tex]p(a)+p(b)[/tex]
⇒ [tex]\frac{1}{6} + \frac{3}{6}[/tex]
⇒[tex]\frac{4}{6}[/tex]
⇒[tex]\frac{2}{3}[/tex]
Hence we can conclude that the probability of rolling 2 or an odd number is 2/3.

Step-by-step explanation:
q(x) is the same as y, so in other words, it was asking you, what is x when y = 0. The solutions of this graph are -4 and a decimal number somewhere near 1.6, and since there is no 1.6 or a decimal number as a choice, its -4 which is the other answer of the graph.

Answer:
Proof of Construction: The compass was used as a measuring tool to obtain (and copy) the length of the given segment. Since the given segment and the copy are the same length, the segments are congruent.
Note: You may also think of the length from A to B as being the radius of a circle with center at A. By copying the circle at A', the radii segments will be congruent.

I WILL GUVE BRAINLIEST!!!!
Answer:
[tex]92\ yd^2[/tex]
Step-by-step explanation:
The given figure is a trapezoid, the formula for finding the area of a trapezoid is the following,
[tex]A=\frac{h(b_1+b_2)}{2}[/tex]
Where (h) is the height of the figure, and ([tex]b_1[/tex]) and ([tex]b_2[/tex]) are the bases. It is given that the height is (8) and ([tex]b_1[/tex]) is (8). The value of ([tex]b_2[/tex]) can be found by adding the value of ([tex]b_1[/tex]) to the "overhang" that ([tex]b_2[/tex]) has over ([tex]b_1[/tex]). Thus, ([tex]b_2[/tex]) is ([tex]8+7[/tex]) or rather ([tex]15[/tex]). Now substitute the values into the equation and solve for the area of the trapezoid,
[tex]A=\frac{8(8+15)}{2}[/tex]
[tex]=\frac{8(23)}{2}[/tex]
[tex]=4(23)[/tex]
[tex]=92[/tex]

Answer:
12
Step-by-step explanation:
Okay, so on a grid, points Q and R are parallel to each other on the point 6, we just have to figure out how far apart they are, and to figure that out, we have to find the distance between 8 and -4 so:
8 - -4 = 8 + 4 = 12
So, the distance from point Q to point R is 12

The Hogan family plans to build a rectangular house corral on their farm with length, L, and width,w. The area needs to be at least 1,900 ft 2 and have a width, w, of 20 ft.
What are the possible lengths, L, of the Hogans' house corral in feet?
Need help asap.
Answer: The length must be at least 95 ft. squared. Pick the line with the filled in left circle, and the right side is an arrow. Put the left side that's filled in on 95 (middle line between 90 and 100).
Step-by-step explanation: Divide the minimum total area by the minimum width. The answer is the minimum length.
Length x Width = Area
20 ft. x 95 ft. = 1900 ft. sq

Answer:
x = 61
Step-by-step explanation:
The two angles add to a right angle, which is 90 degrees
29+x = 90
Subtract 29 from each side
29+x-29 = 90-29
x = 61
Answer:
61 degrees
Step-by-step explanation:
if Y is 29 degrees and the entire angle is a 90 degree angle than x would be 61 degrees to equal a 90 degree angle
