Question

I
The radius of the base and the height of a
cylinder are in the ratio 2:3 . If its
volume is 1617 ans, find the TSA of the
cylinder.​

Answer 1

Step-by-step explanation:

r=2:3

h=?

TSA=?

volume=1617

volume of cylinder=π r^2h

1617. =π(2/3)^2h

1617×7×3/22/2=h

33957/44=h

771.75=h

T.S.A of cylinder=πr(r+h)

= π2/3(2/3+771.75

=4/9π+771.75

=88/63+771.75

=1.39+771.86

=773.14
