Question

What is the volume TSA and CSA of the frustrum of a cone CBSE based .

Answer 1

volume of frustum of cone =1/3πh(R^2+r^2+Rr)
TSA of frustum =πl(R+r)+πR^2+πr^2
CSA of frustum =πl(R+r)

Answer 2

volume if frustum of cone=1/3Πh(r1×r1+r2×r2+r1×r2)
csa of frustum of cone=Πl(r1+r2)
tsa of frustum of cone=Π(r1+r2)+Πr1×r1+Πr2×r2
