Question

The ratio between CSA and TSA is 1:2 find the volume of the cylinder ,given that it's TSA is 616 cm sq

Answer 1

【CSA:TSA=1:2

2K=616

K=308

SO CSA= 308 sq cm】

TSA ============616

Or,Curved SA +2πr^2=616

Or, 308 +2πr^2;= 616

Or,2πr^2 = 308

Or,r^2= 308 ×7/44

r=7 cm

CSA =2πrh =308

2πrh=308

h=(308×7 )/ (44×7)

h=7 cm

Volume of Cylinder =πr^2h

V========22/7 ×7×7×7

V========1078 cubic meter

So volume of the cylinder is 1078 m^3
