Given a cylinder with the radius 5cm and height 8cm. Find the volume of this cylinder. Take π as 3.14.
The picture below shows the cylinder with the radius 5cm and the height 8cm.
To calculate the volume, we can use the formula for the volume of the cylinder. Note that r is the radius and h is the height.
The values for r, h and π are given. So, we just substitute r with 5, h with 8 and π with 3.14.
Now, the calculated number 628 carries no meaning unless we include the unit for it. Since the radius and height are in cm, the unit for volume will be cm3. Hence:
Clearly, the answer is D.
