Yes i already done this question
ok ill send
Csa=2200/20
By this we can find CSA =110
V=22/7×7/4×7/4×10=96.25m^3
My answer is correct or not
bro your answer is correct
i checked
Thanks
I’m sure this is the correct answer

Csa =2*pi*r*h
Csa cost= 2200
2200/20= csa
Csa=110
2*pi*r*h=110
H=10
2*22/7*r*10=110
R=1.75
Volume =pi*r*r*h
V=22/7*1.75*1.75*10
V=96.25
