Question

What is the volume and total surface area of : 1.Cylinder 2.cone 3.cube 4.sphere 5.Hemisphere its urgent

Answer 1

volume of cylinder----π r sq. h
TSA of cylinder--- 2πr( h+r)
cone---- 1/3 π r sq. h
TSA of cone-- πr(l+r)

volume of cube---- a*a*a

sphere--- 4/3πr cube
TSA OF sphere---- 4 πr sq.

hemisphere---2/3 πr cube
TSA of hemisphere-- 3π r sq.

Answer 2

volume of cylinder=πr^2h
t.s.a. of cylinder=2πr(h+r)


volume of cone=1/3πr^2h
tsa of cone=πrl


volume of cube = (side )^3
tsa of cube=6a^2


volume of sphere=4πr^3/3
tsa of sphere=πr^2


volume of hemisphere=2πr^3/3
tsa of hemisphere=3πr^2
