Question 105
A cylinder and a cone have the same height and the same radius of the base. The ratio of the volumes of the cone and cylinder is
Solution
we know that
the volume of the cone is = 1\3 $$\times$$ $$\pi$$ $$\times$$ r^2 $$\times$$ h and
the volume of the cylinder is = $$\pi$$ $$\times$$ r^2 $$\times$$ h then
volume of the cone \ volume of the cylinder = 1\3 $$\times$$ $$\pi$$ $$\times$$ r^2 $$\times$$ h \ $$\pi$$ $$\times$$ r^2 $$\times$$ h
volume of the cone \ volume of the cylinder = 1\3 Answer
