a circle is drawn within as shown. what is the best approximation for the area of the shaded region? use 3.14 for pie

Answers

Answer 1

Answer:

7536 espero que te ayude

Answer 2

21.5in^2 is your answer.
the formula for a circles area is pi•r^2
since the square is the same height as the circle, we can conclude that side length of the square is equal to the diameter of the circle.
the radius (r) is half the diameter.
so using our area formula we will write our formula as 3.14•5^2 and your answer is 78.5. Thats the area of the circle but we are looking for the area of the shaded region. find the area or the square by squaring the side length 10^2 or 10•10. to get the area of the square, 100. now subtract 100-78.5 to get the area of the shaded leftover region.

Answer:

10,500

Step-by-step explanation:

See this as 2 rectangles: a box of water (28cm), and another box with the height you want (35cm)

Area of Rectangle = lwh

For the water;

50 x 30 x 28= 42000

As for the needed volume:

50 x 30 x 35 = 52500

To find how much more water, subtract the smaller volume from bigger volume.

10500 should be the final answer

The answer is 1050.. hope u have a good day

Get the slope of the line using the two known points:

slope = (7 3/4 - 6 1/4) / (1 1/4 - 3/4) = (1 2/4) / (2/4) = 3

Use the point-slope formula for a line to get the equation of the line. You can use any of the known points and the slope computed above. For example,

y - 6 1/4 = 3 (x - 3/4) ⇒ y = 3x + 16/4 = 3x + 4

Then for some given value of x, the third point has y-coordinate 3x + 4.

Step-by-step explanation:

Answer:

205.2

Step-by-step explanation:

First get the area's of the 3 triangles on top of the base, the formula is base x height divided by 2

10 x 9 = 90

90 / 2 = 45

Multiply the area of the 3 sides together :

45 x 3 = 135

Now find the area of the base triangle :

9 x 7.8 = 70.2

To find the surface area of the ENTIRE shape you have to add all the sides :

135 + 70.2 = 205.2

Step-by-step explanation:

So it's easier to find the area when you split the shape into 2 parts, and they already did that for you. So basically you find the area of both triangles and add them together. The formula for a triangle is base x height divided by 2. You don't have to do that because there are 2 triangles with the same base and height so you don't have to divide it by 2. 3 x 4 = 12, so A. 12 square feet is your answer.
