Radius and volume of cone and cylinder are same.Radius and height of cylinder of cylinder are 7 cm and 10 cm respectively.Find the height of the cone.



H(height of cylinder)
volume of the cylinder= \pi  r^{2} H \\ 
 \frac{22}{7} *49*10 \\ 
220*7=1540 cm ^{3}  \\

volume of the cone= \frac{1}{3}  \pi  7^{2} h \\  \\ 
 \frac{1}{3} * \frac{22}{7}* 49*h=1540 \\  \\ 
51.33*h=1540 \\ 
height of the cone=30.0019

no way..my answer is correct
