A soup can has a height of 4 inches and a radius of 2.5 inches. What's the volume of soup in cubic inches that would fill one so
Alenkasestr [34]

Answer:

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:

v=\pi r^2h

We know that the height is 4 inches and the radius is 2.5 inches.

r= 2.5 in

h= 4 in

v=\pi (2.5in)^2*4in

Evaluate the exponent.

(2.5 in)^2=2.5 in*2.5in=6.25 in^2

v=\pi *6.25 in^2*4 in

Multiply 6.25 in^2 and 4 in.

6.25 in^2*4 in=25 in^3

v=\pi*25 in^3

Multiply pi and 25 in^3.

v=78.5398163 in^3

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

v=78.5 in^3

78.5 cubic inches can fill one soup can.
