By using the formula....
volume of frustum=1/3πrh(r^2+R^2+Rr)
curved surface area = πl(R+r)
where l^2= h^2+(R-r)^2
The total surface area of the frustum of the cone = π l(R+r) +πR2 +πr2
volume of frustum=1/3πrh(r^2+R^2+Rr)
curved surface area = πl(R+r)
where l^2= h^2+(R-r)^2
The total surface area of the frustum of the cone = π l(R+r) +πR2 +πr2
