Answer» CSA of frustum = π(R+r)l Volume of embankment = π(R^2-r^2)h Volume of sphere = 4/3πr^3 Volume of cell = 4/3π(R^3-r^3) CSA of cone = πrl TSA of cone = πr( l+r) Volume of cone= 1/3πr^2h CSA of cylinder = 2πrh Slant height = √h^2+r^2 Volume of cube= a^3 Volume of frustum of cone = 1/3πh(r1^2+r2^2+ r1r2) |
