Question

a group of friends just ordered a large pizza of radius 8.5 inches. whats the circumference of the pizza? select one of four 4.25π in. 17π in. 18π in. 72.25π in. remaining attempts: 1

Explanation:

Step1: Recall the formula for circumference

The formula for the circumference of a circle is \(C = 2\pi r\), where \(r\) is the radius.

Step2: Substitute the given radius

Given \(r = 8.5\) inches. Substitute into the formula: \(C=2\pi\times8.5\).

Step3: Calculate the value

\(2\times8.5 = 17\), so \(C = 17\pi\) inches.

Answer:

\(17\pi\) in.
