Question

a toy is a combination of a cylinder and a cone having same radius. lateral height of a cone is 25 cm and volume of the cylindrical part is 2310cm^3 if the height of the cylinder is 15 cm then find the volume of the cone​

Answer 1

Answer:

- Radius of cylinder:

V=2310

h = 15

V = πr 2h

r2=v/πh=2310x7/22x15 = 49

r =v49=7cm

Vol. of Cone:

I = 25, r = 7, h=v 25^2-7^2

h =v625-49=v576=24

volume of CONE = 1/3πr^2h

1/3x22x7^2 x 24/7=1232cm3. Ans
