Final answer:
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.
