Question: What is the volume of a cylinder with a radius of 3 cm and a height of 10 cm? (Use π = 3.14) (2021)

Options:

Correct Answer: 84.78 cm³

Exam Year: 2021

Solution:

Volume = πr²h = 3.14 * (3)² * 10 = 3.14 * 9 * 10 = 282.6 cm³.

What is the volume of a cylinder with a radius of 3 cm and a height of 10 cm? (Use π = 3.14) (2021)

What is the volume of a cylinder with a radius of 3 cm and a height of 10 cm? (Use π = 3.14) (2021)

Step 1: Identify the formula for the volume of a cylinder, which is Volume = πr²h.
Step 2: Substitute the value of π with 3.14.
Step 3: Identify the radius (r) of the cylinder, which is 3 cm, and the height (h), which is 10 cm.
Step 4: Calculate r² (the radius squared). Since r is 3 cm, r² = 3 * 3 = 9 cm².
Step 5: Now substitute r² and h into the formula: Volume = 3.14 * 9 * 10.
Step 6: First, multiply 9 by 10 to get 90.
Step 7: Now multiply 3.14 by 90 to get the final volume: 3.14 * 90 = 282.6 cm³.
