yes.
I would have left it as V(2) = 12π ft^2, which exact.
37.7 is just an approximation.
The formula for the volume of a right circular cylinder is V=πr^2h. If the height, h, is 3 feet, then the volume is a function of the radius, r.
a)write this formula in function notation, where the height is 3 feet.
b) find the volume if the radius is 2 feet.
Answer:
a) V(r)=πr^2(3)
b)V(2)=π(2)^2(3) ---> V=37.7
Is this correct?
