What is the volume, in cubic inches, of a cylinder with a height of 7 inches and a base radius of 2 inches, to the nearest tenths place?
To calculate the volume of a cylinder, you can use the formula V = πr^2h, where r is the radius and h is the height.
In this case, the radius (r) is 2 inches and the height (h) is 7 inches. Plugging these values into the formula:
V = π(2)^2(7)
V = π(4)(7)
V = 28π
To find the volume to the nearest tenths place, we can approximate the value of π to be 3.14:
V ≈ 28(3.14)
V ≈ 87.92 cubic inches
So, the volume of the cylinder to the nearest tenths place is approximately 87.9 cubic inches.
