Q: What is the area of the base of a cone with radius 3? (2023)
Solution:
Area of base = πr² = π(3²) = 9π square units.
Steps: 5
Show Steps
Step 1: Identify the formula for the area of the base of a cone, which is A = πr².
Step 2: Substitute the radius (r) into the formula. Here, the radius is 3.
Step 3: Calculate the square of the radius: 3² = 9.
Step 4: Multiply the result by π: Area = π * 9.
Step 5: Write the final answer: The area of the base is 9π square units.
