Question

If a cone of radius 10.5 cm and height 12 cm is melted and constructed into a cylinder of the same radius, what will be the height of this cylinder

Answer 1

Answer:

Step-by-step explanation:

Radius of cone =10.5

Height of cone = 12

When cone is melted and constructed into a cylinder, the volume of cone will be equal to volume of cylinder hence

Volume of cone =1/3pie × r square × h

Volume of cylinder = pie × r square × h

Radius of cylinder = 10.5 = radius of cone

Answer 2

Answer:

4cm

Step-by-step explanation:

$\frac{1}{3} \pi  r^{2} H\\=\frac{1}{3} \pi  10.5^{2} * 12\\\\=441\pi \\\\441\pi = \pi r^{2}  H\\441\pi = \pi 10.5^{2}  H\\\\441 = 110.25H\\4=H$

Ignore those capital a's i dunno why they are there.
