Question

Use the formula C C = 2pi * r and pi = 3 . 14 to find the circumference of a circle with a radius of 5 meters.

Answer 1

Circumference of circle = 31.4 square meter

Explanation:

Given:

Radius of a circle = 5 meter

Value of π = 3.14

Find:

Circumference of circle using formula "2πr"

Computation:

Circumference of circle = 2πr

By putting value of 'r' and 'π' in given formula

Circumference of circle = 2(3.14)(5)

Circumference of circle = (6.28)(5)

Circumference of circle = 31.4 square meter
