To wrap the cylindrical box, you need to calculate the surface area of the cylinder plus the areas of the top and bottom circles.
The formula for the surface area of a cylinder is:
Surface Area = 2 * pi * r * h + 2 * pi * r^2
where r is the radius of the cylinder and h is the height of the cylinder.
Given:
Radius (r) = 8
Base (h) = 9
Surface Area = 2 * 3.14 * 8 * 9 + 2 * 3.14 * 8^2
Surface Area = 452.16 + 401.92
Surface Area = 854.08 square units
So, you will need approximately 854.08 square units of wrapping paper to cover the top, bottom, and all the way around the cylindrical box.
Use a formula to find the amount of wrapping paper you need to wrap a gift in the cylindrical box shown. You need to cover the top, bottom, and all the way around the box. Use 3.14 for pi.
Radius = 8
Base = 9
