Question

1. what is the circumference of a circle that has a radius of 16 cm?

32π cm
16π cm
256π cm
8π cm

Explanation:

Step1: Recall the formula for the circumference of a circle

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

Step2: Substitute the given radius into the formula

We are given that the radius \( r = 16 \) cm. Substituting this value into the formula, we get \( C = 2\pi\times16 \).

Step3: Simplify the expression

Calculating \( 2\times16 \), we have \( 2\times16 = 32 \). So the circumference \( C = 32\pi \) cm.

Answer:

A. \( 32\pi \) cm
