Multiple choice

The volume of a cylindrical oil can is $3080$ cm$^3$. If the base radius is $10.5$ cm, find the height of the can. $(\pi = 3.142)$

  1. $8.89cm$
  2. $6.89cm$
  3. $4.89cm$

  4. None of these

A Correct answer
Explanation

Volume = pi * r^2 * h. 3080 = 3.142 * (10.5)^2 * h. 3080 = 3.142 * 110.25 * h. 3080 = 346.4 * h. h = 3080 / 346.4 = 8.89 cm.

AI explanation

Using the volume of a cylinder formula, V equals pi times radius squared times height, we solve for height by dividing the volume by pi and the square of the radius. The height equals 3080 divided by 3.142 and 110.25, which simplifies to approximately 8.89 centimeters.
