C. 78.5 in^3
Step-by-step explanation:
A soup can is in the shape of a cylinder. The volume of a cylinder can be found using the following formula:

We know that the height is 4 inches and the radius is 2.5 inches.
r= 2.5 in
h= 4 in

Evaluate the exponent.


Multiply 6.25 in^2 and 4 in.


Multiply pi and 25 in^3.

Round to the nearest tenth. The 3 in the hundredth place tells us to leave the 5 in the tenth place.

78.5 cubic inches can fill one soup can.
