Use a formula to find the amount of wrapping paper you need to wrap a gift in the cylindrical box show. You need to cover the top, bottom, and all the way around the box. Use 3.14 for pie. 8in tall 7in radius

Answer 1

To find the amount of wrapping paper needed to cover the cylindrical box, we need to calculate the surface area of the box.

The formula for the surface area of a cylinder is:

Surface Area = 2πr^2 + 2πrh

Where:
- π is approximately 3.14
- r is the radius of the cylinder
- h is the height of the cylinder

Given:
- Radius (r) = 7 inches
- Height (h) = 8 inches

Plugging in the values into the formula:

Surface Area = 2 * 3.14 * 7^2 + 2 * 3.14 * 7 * 8
Surface Area = 2 * 3.14 * 49 + 2 * 3.14 * 7 * 8
Surface Area = 307.86 + 351.68
Surface Area = 659.54 square inches

Therefore, you would need approximately 659.54 square inches of wrapping paper to cover the cylindrical box.
