Question

The wheels on Noah's bike have a circumference of about 5 feet. About how long is a spoke on the bike wheel that goes from the center to the rim of the wheel? Round to the nearest tenth.

Answer 1

0.8ft

Explanation:

Given the circumference, we want find the diameter, and the radius is the length of the spoke

the expression for circumference is

C=2πr

given

C=5feet

5=2*3.142*r

5=6.284r

Divide both sides by 6.284 we have

5/6.284=r

r= 0.795 ft

to the nearest tenth this is 0.8ft
