You can put this solution on YOUR website!
radius = r = d/2 = 10/2 = 5
height = h = 3*r = 3*5 = 15

V = pi*r^2*h
V = 3.14*r^2*h
V = 3.14*5^2*15
V = 1,177.5

You have the right answer

Since the radius is 1/2 of the diameter:
Radius= 5
Height= 5*3= 15
Area of a circle:
A= Pi*r^2= 3.14*5^2= 3.14*25= 78.5
And the volume:
V= A*Height= 78.5*15= 1,177.5 cubic (inches, centimeters, whatever)
