Question

The nets below represent a small cylindrical storage container

7.5 in.
4 in.

Find the amount of material needed to make this container.

Use 3. 14 for pi

188.40 in2
100.48 in²
150.23 in²
288.88 in²

Answer 1

To find the amount of material needed to make the container, we need to calculate its lateral surface area.

The lateral surface area of a cylinder is given by the formula:

Lateral surface area = height x circumference

where circumference = 2 x pi x radius

In this case, the height is 7.5 inches and the radius is 4 inches.

Circumference = 2 x pi x radius = 2 x 3.14 x 4 = 25.12 inches

Lateral surface area = height x circumference = 7.5 x 25.12 = 188.4 square inches

Therefore, the amount of material needed to make the container is 188.40 in². Answer: A.
