So the formula for area of a circle is A=πr^2
We know that the diameter (or distance across) one blue half-circle is 40 yards
And radius is half of the diameter so 40/2 = 20 so radius=20
Now just plug it into the equation! A = π (20)^2 —> A = π (400) —> A = 1256
BUT that is the equation to find area of a complete circle. Since this is a HALF circle, divide that area in half: 1256/2 = 628
So the area of one of the blue half-circles is 628

5. Use 3.14 for π to estimate the area of a circle. The diameter is given. Round your answer to the nearest hundredth if necessary.
Answers
Step-by-step explanation:
the radius of a circle is half of the diameter
= 24.4/2 = 12.2 m
the area of a circle is
pi × r²
r being the radius.
so, in our case that is
3.14 × 12.2² = 3.14 × 148.84 = 467.3576 ≈ 467.36 m²

B. x = 23
C. x = 48
D. x = 56
Answers
Answer:
x = 19
Step-by-step explanation:
x + (x + 4) + (3x - 9) = 90°
Combine like terms
5x - 5 = 90
Add 5 on both sides
5x = 95°
Divide 5 on both sides

Pick one of these answer choices.

Step-by-step explanation:
We add the positive additions of nails: 12 + 2 1/2 = 14 1/2 pounds of nails
We subtract the negative subtractions of nails: 14 1/2 - 1 1/4 - 3 9/20 = 9.8 pounds of nails.

Answer:
The radius and the diameter of the circle are 11 cm and 22 cm respectively.
Step-by-step explanation:
The radius of a circle is a line segment extending from the center of a circle or sphere to the circumference or bounding surface, while the diameter of a circle is a straight line passing from side to side through the center of a body or figure, commonly a circle or sphere. Since the diameter goes entirely across the circle while passing through the midpoint - or center - of a circle and the radius only goes from the edge to the midpoint, that means the diameter is twice as big as the radius. In this example, the radius is already given to you, which is 11 cm, based on the image. Using this, you can figure out the diameter of that circle would be [tex]11 * 2[/tex] or 22 cm. So the radius of the circle is 11 cm, while the diameter of the circle is 22 cm.

Each bracelet takes 1/6 yard of wire to make.
Marianna starts with 2 yards of wire, and ends with 2/3 yard remaining.
First, change all terms to be over 6:
1/6 = 1/6
2 x 6/6 = 12/6
2/3 x 2/2 = 4/6
12 yards of wire - 4 yards of wire = 8 yards of wire. Each bracelet uses 1 yard, ∴ 8 bracelets are made.
8 bracelets is your answer.

GIVEN :-
Flat fee = $5Amount you receive on walking a mile = $2TO FIND :-
Expression for the total money you'll collect from your sponsorMoney you receive for walking 20 milesPROCEDURE :-
Lets assume that you walk 'x' miles.
For 1 mile , you'll get $2.
⇒ For 'x' miles , you'll get = [tex]2 \times x[/tex] = $(2x)
So,
Total money you'll receive from your sponsor after walking 'x' miles = (Flat fee) + (Amount you'll receive for walking 'x' miles)
⇒ $5 + $(2x)
⇒ $(2x + 5)
∴ Money you'll receive after walking 20 miles = $(2 × 20 + 5) = $45

GIVEN :-
Number of tomatoes he already has = 6Number of tomatoes needed to win the contest = 30Number of tomatoes he needs to produce per week = 8TO FIND :-
Number of weeks he needs to produce 30 tomatoesPROCEDURE :-
Let the number of weeks he needs to produce 30 tomatoes be x.
In 1 week , he needs to produce 8 tomatoes.
⇒ In 'x' weeks , he needs to produce = [tex]8 \times x = 8x[/tex] tomatoes.
So,
(Number of tomatoes he produces in 'x' weeks) + (number of tomatoes he already has) = Number of tomatoes he needed to win the contest
⇒ [tex]8x + 6 = 30[/tex]
⇒ [tex]8x = 30 - 6 = 24[/tex]
⇒ [tex]x = \frac{24}{8} = 3[/tex]
∴ He needs 3 weeks to produce 30 tomatoes.

What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.
One pizza was cut into 12 pieces. Eddie ate 1/12 and Melanie ate 1/12. Mom ate 1/6 and dad ate 1/4. Albert ate 1/6 of the pizza.
Then the amount of pizza that leftover will be
⇒ 1 - (1/12) - (1/12) - (1/6) - (1/4) - (1/6)
⇒ 1 - (1/12) - (1/12) - (2/12) - (3/12) - (2/12)
⇒ 1 - [(1 + 1 + 2 + 3 + 2) / 12]
⇒ 12 / 12 - 9 / 12
⇒ (12 - 9) / 12
⇒ 3 / 12
⇒ 1/4
The amount of pizza that is left over will be 1/4. Then the correct option is E.
