Question

If she wants to track to have a circumference of 150 feet , what does the radius of the track need to be?

Answer 1

we are given that

she wants to track to have a circumference of 150 feet.

we have been asked to find

what does the radius of the track need to be?

As we know that

`Circumference=2\pi r`

Substitute the values we get

`150=2 \pi r\\ \\ r=(75)/(\pi) \\ \\ r=(75)/(22/7)\\ \\ r=(75*7)/(22)=  23.863feet`

Hence radius=23.863 feet.
