Volume of a cylinder with a diameter of 6 inches and a height that is three times the radius

254.47 i think

Answer: 254.47 cubic inches

Step-by-step explanation:

You are told that d = 6 so since the radius is half the diameter, r = 3. Use this to find h: h is 3 times the radius so h = 3 times 3 = 9. Now use the formula for the volume of a cylinder and plug in these values:

V = pi r^2 h

V = pi (3) ^2 (9) = 81pi = 254.47 cubic inches
