Question

If you were to cover a pizza with cheese, how much area, rounded to the nearest whole number, would you need to cover with cheese if the pizza had a circumference of 31.4 inches?

Answer 1

Answer:

79 square inches

Step-by-step explanation:

First, let's find the diameter given the circumference.

• $C=\pi d$
• $d=\frac{C}{\pi }$
• $d= 31.4/3.14$
• $d=10$

Next, we know the the radius is half the diameter, so the radius is 5 inches. Now, we can solve the area of the circle.

• $3.14 * 5^2$
• $3.14 * 25$
• $78.5$
• 78.5 ≈ 79 square inches

Therefore, the answer is 79 square inches.
