Jermaine has a mailing cylinder for posters that measures 18 inches long and 6 inches in diameter. What volume can it hold? Use
worty [1.4K]

<u><em>Answer:</em></u>

The cylinder can hold 508.68 in³

<u><em>Explanation:</em></u>

<u>The volume of a cylinder can be calculated using the following rule:</u>

Volume of cylinder = πr²h cubic units

where r is the radius of the cylinder and h is its height

<u>Now, we are given that:</u>

height of cylinder = 18 in

diameter of cylinder = 6 in which means that the radius of the cylinder is 3 in

π is 3.14

<u>Substitute with the givens in the above equation to get the volume of the cylinder as follows:</u>

Volume of cylinder = πr²h

Volume of cylinder = 3.14 * (3)² * 18

Volume of cylinder = 508.68 in³

Hope this helps :)

A circle with a radius of 5 sits in a 11 X 11 rectangle. What is the area of the shaded region?
Nataly_w [17]
Hi :) I'm guessing the shaded region is the region inside the rectangle but outside the circle.

To solve this problem, you need to find the area of the rectangle and area of the circle. Then subtract the circle's area from the rectangle's.

Area of a rectangle: length × width
The problem already tells you the area of the rectangle, because it says it is an 11 × 11 rectangle.
(11)(11) = 121

Area of rectangle: 121 units²


Area of a circle: \pi r^2
Plug in 5 for the radius r.

\pi 5^2 = 78.5

Area of circle: 78.5 units²


Now subtract 78.5 from 121.
121 - 78.5 = 42.5

The area of the shaded region is 42.5 units².
