Question

A. right cylinder has a radius of 2 units and a height of 5 units. a right cylinder has a radius of 2 units and a height of 5 units. what is the volume of the cylinder? round to the nearest tenth.

A. 31.4 cm³
B. 62.8 cm³
C. 157.1 cm³
D. 314.2 cm³

Answer 1

The volume of the cylinder with a radius of 2 units and a height of 5 units is calculated using the formula V = πr²h, resulting in a volume of 62.8 cm³ when rounded to the nearest tenth. Hence, option (B) is correct.

Step-by-step explanation:

To find the volume of a cylinder, we can use the formula V = πr²h, where V is the volume, r is the radius, and h is the height.

Given that the radius is 2 units and the height is 5 units, we can substitute these values into the formula:

V = 3.142 × (2 units)² × 5 units

V = 3.142 × 4 units × 5 units

V = 62.84 units³

Rounding to the nearest tenth, the volume of the cylinder is approximately 62.8 cm³. Therefore, the correct answer is option B. 62.8 cm³.
