Question

A circle has a circumference of 150 meters. what is the measure of its radius?

Answer 1

Answer: 23.9 meters
Explanation: formula is 2pi(r) or 2 times pi times radius

C=2pi(r)
150=2(3.14)r
150=6.28r
150/6.28=23.9
R=23.9
*rounded to the nearest tenth!

Hope this helps :)

Answer 2

Answer:23.87

As we know,formula of a circle is the circumference multiplied by diameter.

`\pi d` or
`2 \pi r`

Substituting in this equation now

`2\pi r=C\\= > 2*\pi *r=150\\= > \pi r=75\\= > r=(75)/(\pi ) \\= > 23.87(approx)`

OR 23(rounding)
