Answer:

using 3 for pi it's V = 960cm^3

Step-by-step explanation:

R is the radius, which as stated, is half the diameter.

r = 8cm / 2 = 4cm

H is the height, which is shown to be 20cm

h = 20cm

V = pi*r^2*h

V = pi*(4cm)^2*20cm

substituting 3 for pi as requested.

V = 3*(4cm)^2*20cm - 3 * (16cm^2) * 20cm = 48cm^2 * 20cm = 960cm^3
