Question

Find the height of cylinder whose radius is 7 cm and total surface area is 968 cm2.

Answer 1

this is your answer hope it will help u

Answer 2

Formula total surface area of cylinder=$\bold\pink{2 \ pi \ r}$

Total Surface Area=$\bold\green{968}$

2×$\: \: \: \dfrac {22} {7}$

7(7+h)=968

2×22(7+h)=968

(7+h)=$\: \: \: \ {968} {44}$

7+h=22

h=22-7

h=15 cm.

Hence height of cylinder is $\bold\purple{15 \ cm}$
