A cylinder has a base diameter of 20 meters and a height of 5 meters. What is its volume in cubic meters, to the nearest tenths place?
To calculate the volume of a cylinder, we use the formula:
Volume = π * r^2 * h
where r is the radius of the base (half of the diameter) and h is the height.
Given that the base diameter is 20 meters, the radius (r) is half of the diameter, so r = 20/2 = 10 meters.
Plugging in the values for r and h into the formula, we get:
Volume = π * 10^2 * 5
Volume = π * 100 * 5
Volume = π * 500
Volume ≈ 1570.8 cubic meters
Therefore, the volume of the cylinder is approximately 1570.8 cubic meters to the nearest tenths place.
