Question

Find the circumference of a circle with a radius of 15 centimeters. Round your answer to the nearest centimeter

Answer 1

94 cm

Explanation:

The formula for finding the circumference of a circle is;

Circumference = 2πr

where π =
`(22)/(7)` or 3.14 and

r = radius

Here radius is 15 cm so;

Circumference =
`2 * (22)/(7) * 15`

=
`(660)/(7)`cm

= 94.28cm

= 94 cm ( rounded to the nearest centimetre )
