Multiple choice

If the radius and height of a right circular cylinder are $4$ cm and $7$ cm respectively, then its volume will be

  1. $314\ \text{ cm }^{ 3 }$
  2. $315\ \text{ cm }^{ 3 }$
  3. $350\ \text{ cm }^{ 3 }$
  4. $352\ \text{ cm }^{ 3 }$

D Correct answer
Explanation

Volume of a cylinder = pi * r^2 * h. Using pi = 22/7, r=4, h=7: Volume = (22/7) * 16 * 7 = 22 * 16 = 352.

AI explanation

The volume of a right circular cylinder is calculated using the formula pi * r^2 * h. Substituting the given radius of 4 cm and height of 7 cm, and using pi as 22/7, the expression becomes (22/7) * (4)^2 * 7. This simplifies to 22 * 16, which equals 352 cubic cm.
