An oatmeal container has a diameter of 9 inches and a volume of 239.4 in3. What is the lateral surface area of the oatmeal container? Hint: You have to use the Volume to find the height before you can calculate the lateral surface area. Round your answer to the nearest tenth.

Lateral surface area = 106.4 .

Step-by-step explanation:

Assumed that the oatmeal container has the shape of a cylinder. Its lateral surface area can be determined by:

lateral surface area = 2rh

But,

volume = h

where: r is the radius, and h is the height.

From the question, volume = 239.4 , and diameter = 9 inches, then;

radius = =

          = 4.5

radius = 4.5 inches

Thus,

volume = h

239.4 = x x h

          = 20.25h

h =

  =

h = inches

Therefore,

lateral surface area = 2rh

                                = 2(4.5)()

                                = 2 x 4.5 x 11.8222

                                = 106.3998

Lateral surface area of the oatmeal container is 106.4 .
