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?
a π(8.3)^2
b 2π(8.3)
c π(11.1)^2
d 2π(11.1)
The correct answer is c) π(11.1)^2.
The formula for the area of a circle (which represents the base of the cylinder) is A = πr^2, where r is the radius of the circle. In this case, the radius would be half of the diameter, which is given as 11.1 inches.
So, substituting the value of the radius into the formula for the area of a circle, we get:
B = π(11.1)^2
Therefore, the expression that can be used to find the value of B, in square inches, for this cylinder is c) π(11.1)^2.
