Question

Pizza World sells an extra-large pizza with a radius of 10 inches. What is the circumference of the crust of the extra-large pizza? (Use 3.14 for π and round the answer to the nearest hundredth if necessary)

a) 62.80 inches
b) 31.40 inches
c) 18.85 inches
d) 15.70 inches

Answer 1

Option A. The circumference of the crust of the extra-large pizza is approximately 62.80 inches.

Step-by-step explanation:

To find the circumference of the crust of the extra-large pizza, we can use the formula for the circumference of a circle, which is C = 2πr. Given that the radius of the pizza is 10 inches, we can substitute this value into the formula.

C = 2 × 3.14 × 10

C = 62.80 inche

Therefore, the circumference of the crust of the extra-large pizza is approximately 62.80 inches (option a).

The question asks for the circumference of the crust of an extra-large pizza with a radius of 10 inches. To calculate the circumference of a circle, you would use the formula C = 2πr, where C is the circumference, π is pi (approximately 3.14), and r is the radius of the circle. Replacing the value of r with 10 inches, we get C = 2 × 3.14 × 10. Performing the multiplication, we obtain C = 62.80 inches, which is the circumference of the pizza's crust.
