The function V(r)=10πr2 represents the volume of a cylinder that is 10 inches high with a radius of r. Which is the correct interpretation for the function notation V(3)=90π ?

Question

a. a radius of 3 gives the value 90
b. the volume of the cylinder is 3 when the radius is 90π
c. the volume of the cylinder is 90π when the radius is 3
d. a cylinder of 90π is produced from a radius of 3

Answer 1

The function notation \( V(3) = 90\pi \) means that when the radius \( r \) is 3, the volume \( V \) of the cylinder is \( 90\pi \).

Therefore, the correct interpretation is:

c. the volume of the cylinder is 90π when the radius is 3.
