Multiple choice

If the volume of right cylinder with radius $2$ cm is $\displaystyle 100\pi\ { cm }^{ 3 }$, then the height of cylinder (in cm) is

  1. $20$
  2. $25$
  3. $40$
  4. $50$

B Correct answer
Explanation

Volume = pi * r^2 * h. 100 * pi = pi * 2^2 * h. 100 = 4 * h. h = 25.

AI explanation

The volume of a cylinder is given by the formula V = pi * r^2 * h. Setting up the equation with the given values results in 100 * pi = pi * (2)^2 * h. Solving for h gives 100 * pi = 4 * pi * h, so h = 25 cm.
