Cylinder: Radius:: 3 Height: 9
Part A: what's the area of once circle base?
Par B: Volume of the cylinder?
do not round anything
Part A: The area of one circle base of the cylinder can be found using the formula for the area of a circle, which is A = πr^2.
Given the radius, r = 3, the area of one circle base would be A = π(3)^2 = π(9) = 9π.
Part B: The volume of a cylinder can be found using the formula V = πr^2h, where r is the radius and h is the height of the cylinder.
Given the radius, r = 3, and height, h = 9, the volume of the cylinder would be V = π(3)^2(9) = π(9)(9) = 81π.
