A cylinder and its dimensions are shown. One equation for calculating the volume of a cylinder is V = Bh , where B represents the area of the base of the cylinder. Which expression can be used to find the value of B, in square inches, for this cylinder?

Question

8.3 11.1

Responses
A π
π ( 8.3 ) 2
B 2π(8.3)2π(8.3)
C π
π ( 11.1 ) 2
D 2π(11.1)

Answer 1

The correct expression that can be used to find the value of B, in square inches, for this cylinder is π ( 8.3 ) 2.

This is because the formula for calculating the area of a circle, which is the base of the cylinder, is A = πr^2. In this case, the radius of the circle is 8.3 inches, so the expression π ( 8.3 ) 2 represents the area of the base, which is what B represents in the equation V = Bh.
