Find the volume, in cubic inches, of a cylinder with a diameter of 16 inches and a heigh of 7 inches. use 3.14 for pi. round your answer to the nearest hundredth.

Question

solve using the formula V = πr2h

Answer 1

To find the volume of a cylinder, we can use the formula V = πr^2h, where r is the radius and h is the height.

Given that the diameter of the cylinder is 16 inches, we can find the radius by dividing the diameter by 2:

radius = diameter/2 = 16/2 = 8 inches

Now, we can substitute the values of the radius and height into the formula:

V = π(8^2)(7)
V = 3.14(64)(7)
V = 3.14 * 448
V = 1408.32

Therefore, the volume of the cylinder is approximately 1408.32 cubic inches rounded to the nearest hundredth.

Answer 2

Use the formula
V = πr2h
V = π(7)^2(5)

Answer 3

To find the volume of a cylinder, we can use the formula V = πr^2h, where r is the radius and h is the height.

We are given the radius as 7 inches and the height as 5 inches.

Now, we can substitute the values of the radius and height into the formula:

V = π(7)^2(5)
V = 3.14 * 49 * 5
V = 769.3

Therefore, the volume of the cylinder is approximately 769.3 cubic inches rounded to the nearest hundredth.
