Question

The kids are racing around a circle on the playground with a radius of 12 feet. If they ran around it 5 times, how far did they run round to the nearest foot?

Answer 1

Answer:

377 feet

Step-by-step explanation:

Find the circumference on the circle, using the formula C = 2$\pi$r

Plug in 12 as r, the radius, then solve:

C = 2$\pi$r

C = 2$\pi$(12)

C = 24$\pi$

Multiply this by 5, since the kids ran around it 5 times:

24$\pi$(5)

= 120$\pi$

To the nearest foot, this is 377.

So, the kids ran round 377 feet
