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 .
