Answer:
75.36
Explanation:
r = radius
pi = 3.14
You know the diameter (2*r) is equal to 24 feet
using the formula for diameter you get 2r = 24
now, you can either solve for r (radius) and plug radius into the formula for circumference OR you can use the 2*r value of 24 feet and plug that into the formula for circumference
if you solved for r directly, you would get r = 12
- then you plug r into the circumerference formula 2*pi*r (where pi 3.14) and you would get 75.36
if you used the diameter value of 2*r, all you would have to do is multiply the given diameter value by pi (3.14) and you would get 75.36
UNIT: feet
NOTE
- you can use the diameter value and simply multiply that by pi because the formula for diameter is 2*r and the formula for circumference is 2*r*pi
I hope this helped :)
