Step-by-step explanation:
Cir=30π=2πr , thus r=15 , Area=π(r^2)=225 pie meters
1 mile * (1 hr / 4 mile) = 1/4 hr
1/4 hr = 15 min
This is most likely the answer
Find thy radius.
Thy radius is 7.25 (D / 2 = R)
Thy formula for area is A = (pi)r^2
Substitute and Solve
A = (pi)r^2
= (pi)(7.25)^2
= (pi)(52.5625)
= 165.04625
Therefore, the area is about 165.
