Question

The circumference of the base of a right circular
cylinder is 77 cm. If its height is 21 cm, find the
volume of the cylinder.​

Answer 1

Answer: 9908

Step-by-step explanation: If the circumference is 77, the radius must be (77/2*pi), which is (38.5/pi).

The volume of a cylinder is pi*(radius)^2* height, which is pi*(38.5/pi)^2 * 21,

which is about 9908

Answer 2

Answer:39616.5cm cube

Step-by-step explanation:

2pie×r=77

r=49/2

22/7×49/2×49/2×21=39616.5
