Question

You have a coin bank in the shape of a cylinder. It has a radius of 1.5 inches and a height of 5 inches. What is the surface area of the coin bank? Use 3.14 to approximate pi. Round your answer to the nearest hundredth.

Answer 1

61.23 square inches

Explanation:

Answer 2

Total surface area =61.23 in ^2

Explanation:

To find the total surface area of a cylinder, we use the formula

T . S . A . = 2 π r h + 2 π r^ 2

where r is the radius and h is the height

We know the radius is 1.5 and the height is 5

Substituting the values into the equation

T . S . A . = 2 π (1.5)(5) + 2 π (1.5) ^2

= 15 π +4.5 π

= 19.5 π

Using 3.14 for π

= 19.5 * (3.14)

=61.23 in ^2
