Question

The base radii of two cylinders are in the ratio 2:3 and their height are in the ratio 3:2 .Find the ratio of their volume

Answer 1

Step-by-step explanation:

Let the radii be 2x and 3x, let the height be 5y and 3y. so, ratio of volume =r²h/R²H =(2x)²×5y/(3x)²×3y =20x²y/27x²y =20/27, ratio of CSA =rh/RH =2x×5y/3x×3y =10xy/9xy =10/9.
