Question

In which figure is the height of the cylinder half the radius? A cylinder with a height of 2 and diameter of 8. A cylinder with a height of 4 and diameter of 8. A cylinder with a height of 8 and diameter of 8. A cylinder with a height of 16 and diameter of 8.

Answer 1

a

Explanation:

Answer 2

A) A cylinder with a height of 2 and a diameter of 8.

Explanation:

The height of the cylinder is half the radius. Therefore.

Height of the cylinder = (half of the radius)/2

Answer choice A) A cylinder with a height of 2 and a diameter of 8.

Note that a diameter is found using the following formula:

d (diameter) = 2r (radius).

First, divide 2 from the diameter to find the radius:

8/2 = 4

Next, divide by 2 again to find the height of the cylinder:

4/2 = 2

In this case, the height of the cylinder is 2, ∴ the choice is correct.
