Find the volume of a cylinder that has a diameter of 7 and a height of 8

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.

choice b is correct

step-by-step explanation:

we have been given the following system of inequalities;

we are required to graph the solution to the system of inequalities. using a graphing tool, the graph of the system is as shown in the attachment. the continuous line represents the graph of while the dotted line represents .

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing
