Answer 1

The volume of the cylinder with a radius of 0.750 cm and a height of 5.25 cm is calculated using the formula V = πr²h, which gives a result of 9.278 cm³ when using 3.14 for π.

Step-by-step explanation:

The volume of a cylinder can be calculated using the formula V = πr²h, where π (pi) is approximately 3.14, r is the radius of the cylinder's base, and h is the height of the cylinder. To calculate the volume of a cylinder with a radius of 0.750 cm and a height of 5.25 cm, we substitute these values into the formula:

V = 3.14 × (0.750 cm)² × 5.25 cm

First, calculate the radius squared (r²):

• (0.750 cm)² = 0.5625 cm²

Then multiply by π (pi) and the height (h):

• 3.14 × 0.5625 cm² × 5.25 cm = 9.278 cm³

Therefore, the volume of the cylinder is 9.278 cm³.
