Hello!
To volume of a cylinder is found by using the formula, V = πr²h. In this formula, V is the volume, r is the radius, and h is the height.
We are given the height, but not the radius. Although, we're given the diameter, and half the diameter is the radius.
7 units / 2 = 3.5 units | The radius of the cylinder is 3.5 units.
With all the appropriate values, we can find the volume.
V = π(3.5)²(8)
V = 12.25(8)π
V = 98π, 307.72 (multiplied by 3.14), 307.88 (multiplied by π).
Therefore, the volume of the cylinder is 98π units.
