The solution is in pic

Well i am not sure about ans but the method is right

Answer 2

Answer:

Step-by-step explanation:

2πrh=528

rh=528*7/2*22

rh=84

h=84/r......(1)

πr^h=2772

Use eq.1 in this

πr^2 84/r=2772

84r=2772*7/2*22

r=21/2......(2)

Diameter=2r

Use eq.2 d=2*21/2

D=21

Now,use eq 2 in 1

h=84/r

h=84/21*2

h=8
