Multiple choice

The volume of a cylinder is 3080 $cm^3$ and radius is 7 cm, height is---

  1. 15 cm

  2. 20 cm

  3. 10 cm

  4. None of these

B Correct answer
Explanation

The volume of a cylinder is pi * r^2 * h. Given V = 3080 and r = 7, 3080 = (22/7) * 7^2 * h. 3080 = 22 * 7 * h = 154 * h. h = 3080 / 154 = 20 cm.

AI explanation

Using the volume of a cylinder formula, V equals pi times r squared times h. Substituting the given values gives 3080 equals 22 over 7 times 7 squared times h. This simplifies to 3080 equals 154 times h, so h equals 3080 divided by 154, which is 20 cm.
