Question

enter the correct answer.
calculate the circumference.
formula: c = 2πr
use 3.14 for π.
c = ? cm
round to the nearest tenth.
(the circle has a radius of 10 cm, and there is a diagram of the circle with the radius labeled 10 cm and the circumference marked with ? cm)

Explanation:

Step1: Substitute the value of radius into the formula

Given \(r = 10\) cm and \(\pi=3.14\), substitute into \(C = 2\pi r\).
\(C=2\times3.14\times10\)

Step2: Calculate the result

First, \(2\times10 = 20\). Then \(20\times3.14=62.8\)

Answer:

\(62.8\)
