Find the volume of a cylinder that is 5.2 across and 11.2 tall.
To find the volume of a cylinder, you can use the formula V = πr^2h, where r is the radius of the base and h is the height of the cylinder.
Given that the diameter of the cylinder is 5.2, the radius (r) is half of the diameter, so the radius is 5.2 / 2 = 2.6.
Plugging in the values of r = 2.6 and h = 11.2 into the formula, we get:
V = π(2.6)^2(11.2)
V ≈ 3.1416 * 6.76 * 11.2
V ≈ 238.08 cubic units
Therefore, the volume of the cylinder is approximately 238.08 cubic units.
