A cylinder has a base diameter of 8 inches and a height of 7 inches. What is its volume in cubic inches, to the nearest tenths place?
To calculate the volume of a cylinder, you use the formula V = πr^2h, where r is the radius and h is the height.
Given that the base diameter is 8 inches, the radius is half of the diameter, making the radius 4 inches.
Plugging in the values:
V = π(4)^2(7)
V = π(16)(7)
V = 112π
Now, approximate the value of π to be 3.14:
V = 112(3.14)
V = 351.68
Therefore, the volume of the cylinder is approximately 351.7 cubic inches.
