Answer:
Height = 3.04 units.
Explanation:
Given : A cylinder with radius 3 units is shown below. It's volume is 86 cubic units .
To find : find the height of the cylinder.
Solution : We have given radius = 3 units .
Volume = 86 cubic units .
Volume of cylinder = pi (radius)² height.
Plugging the values.
86 = 3.14 * (3)²* height.
86 = 3.14 * 9 * height.
86 = 28.26 * height .
On dividing both sides by 28.26
Height = 3.04 units.
Therefore, Height = 3.04 units.
