Question

The function V(r)=10πr^2
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
?(1 point)
Responses

The volume of the cylinder is 90π
when the radius is 3.
The volume of the cylinder is 90 pi when the radius is 3.

A radius of 3 gives the value 90.
A radius of 3 gives the value 90.

The volume of the cylinder is 3 when the radius is 90π
.
The volume of the cylinder is 3 when the radius is 90 pi .

A cylinder of 90π
is produced from a radius of 3.

Answer 1

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

(Plugging r = 3 into V(r) = 10πr^2 gives V(3) = 10π·3^2 = 90π.)
