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

Solution:

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

$150=2 \pi r\\ \\ r=\frac{75}{\pi} \\ \\ r=\frac{75}{22/7}\\ \\ r=\frac{75*7}{22}= 23.863feet$

Hence radius=23.863 feet.
