Jo was comparing two cylinders that both had a radius of 5cm. The first had a height of 10cm, and the other a height of 20cm. How many times greater was the volume of the larger cylinder?

Final answer:

The volume of the larger cylinder is 2 times greater than the volume of the smaller cylinder.

Step-by-step explanation:

The volume of a cylinder is calculated using the formula V = πr²h, where V is the volume, r is the radius, and h is the height.

For the first cylinder with a radius of 5cm and a height of 10cm, the volume is calculated as:

V₁ = 3.142 × (5 cm)² × 10 cm = 785.5 cm³

For the second cylinder with a radius of 5cm and a height of 20cm, the volume is calculated as:

V₂ = 3.142 × (5 cm)² × 20 cm = 1571 cm³

To find the relationship between the volumes, we can divide the volume of the larger cylinder by the volume of the smaller cylinder:

V₂ / V₁ = 1571 cm³ / 785.5 cm³ = 2

Therefore, the volume of the larger cylinder is 2 times greater than the volume of the smaller cylinder.
