Answer:

The total volume of juice in a six-pack is 254.3\ in^{2}

Step-by-step explanation:

step 1

Find the volume of one can

The volume of the cylinder (can of juice) is

V=\pi r^{2} h

we have

r=3/2=1.5\ in ----> the radius is half the diameter

h=6\ in

assume

\pi =3.14

substitute

V=(3.14)(1.5)^{2} (6)

V=42.39\ in^{2}

step 2

Find the total volume of juice in a six-pack

Multiply the volume of one can by 6

42.39*(6)=254.3\ in^{2}
