Answer:
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.
