Question

What is the approximate circumference of a circle that has a radius of 90? Use 3.14 for π and express your answer to the tenths place. fill in the blank

__

Answer 1

565.2

Explanation:

Given,

Radius ( r ) = 90

π = 3.14

To find : Circumference of a circle

Formula

Circumference of a circle = 2πr

Circumference of a circle

= 2 x 3.14 x 90

= 6.28 x 90

= 565.2

Answer 2

565.2

Explanation:

The circumference of a circle is given by

C = 2 * pi * r

C = 2 * (3.14) * 90

C =565.2
