Multiple choice

Calculate the volume of the following cylinders. Base radius $= 5$ cm; Length $= 8$ cm $(\pi = 3. 142)$

  1. $628.4$ cm$^3$
  2. $728.4$ cm$^3$
  3. $828.4$ cm$^3$

  4. None of these

A Correct answer
Explanation

Volume of cylinder = pi * r^2 * h = 3.142 * 5^2 * 8 = 3.142 * 25 * 8 = 3.142 * 200 = 628.4.

AI explanation

Using the cylinder volume formula V = pi * r^2 * h, we substitute the radius of 5 cm and the length of 8 cm. This gives V = 3.142 * 5^2 * 8. Calculating the values results in 3.142 * 25 * 8, which equals 628.4 cm^3.
