Pizza pizz solve this queastion

Answer 1

Answer:

Step-by-step explanation:

Given:-

CSA of a cylinder/TSA of a cylinder=1/2

2πrh/2π(h+r)r=1/2

h/h+r=1/2

By cross multiplication,. 2h=h+r

h=r

Therefore,

TSA of a cylinder= 616cm^2

2πr(h+r)=616

r(h+r)=616/2π

r(r+r)=98

r(2r)=98

2r^2=98

r^2=49

r=7cm

h=r=7cm

Volume of a cylinder=2πrh

=2×22/7×7×7

=308cm^3
