Question

Consider the circle with a radius of 30 cm. What is the approximate circumference of the circle? (use 3.14 as an approximation of pi.)

Answer 1

Answer: 188.4 cm

Explanation:

Given

the radius of the circle is
`r=30\ cm`

Also, circumference is given by
`P=2\pi r`

Putting values

`\Rightarrow P=2* 3.14 * 30=188.4\ cm`

The circumference of the circle is
`188.4\ cm`
