Question

If the volume of a cylinder is 3080cm^3and the base radius is 7cm,find the height of the cylinder.Also,find the curved surface area and total surface area

Answer 1

Answer:

Volume= 3080cm³

base radius=>7cm

Step-by-step explanation:

volume=> 3080

=>. πr²h= 3080

=> 22/7 X 7²h =3080

=> h => 3080/(22*7)

=> h= 20cm

Now,

CSA => 2πrh

=> 2*(22/7)*7*20

=>380cm²

TSA=> 2πr(r+h)

=> 2*(22/7)*7(7+20)

=>1188cm²
