Question

The formula for the circumference, C, of a circle with given radius, r, is C = 207. What is the circumference of a circle with a radius of 3 meters? ( (Use a as an estimate for .) A. 7 meters B. 11 meters O c. 22 meters O D. 14 meters

Answer 1

Answer:

22 meters

Explanation:

The circumference of a circle is expressed as;

C = 2 pi r

r is the radius of the circle

Given

radius r = 3 1/2meters

pi = 22/7

Substitute into the formula

Circumference of the circle = 2 * 22/7 * 3 1/2

Circumference of the circle = 2 * 22/7 * 7/2

Circumference of the circle = 44*7/14

Circumference of the circle = 44/2

Circumference of the circle = 22meters

Hence the Circumference of the circle is 22 meters
