Question

A cylinder has a surface area of 234π meters with a radius of 9 m. What is the volume of the cylinder? Leave your answer as π

Answer 1

Answer:

Step-by-step explanation:

surface area of cylinder=2$\pi$rh

              or,234$\pi$=2*22/7*9*h

              or,234*22/7=396/7*h

              or,5148/7=396/7*h

               or,36036=2772h

                or,36036/2772=h

                   h=13

now,

     volume=$\pi$r^2h

                  =22/7*(9)^2*13

                  =3309.4285
