Question

Ileana buys a large circular pizza that is divided into eight equal slices. She measures along the outer edge of the crust from one piece and finds it to be 512 inches. What is the diameter of the pizza to the nearest inch? A.4 in. B.7 in. C.8 in. D.14 in.

Answer 1

Answer:

14 inches

Step-by-step explanation:

She measures along the outer edge of the crust from one piece and finds it to be 5.5 inches.

We need to find the diameter of the pizza. A pizza is divided into 8 equal parts.

The circumference of one part = $\dfrac{2\pi r}{8}=\dfrac{\pi r}{4}$

So,

$\dfrac{\pi r}{4}=5.5\\\\2r=D=14\ inch$

So, the diameter of the pizza is 14 inches.
