What is the area of a circle with a diameter of 16 cm? (2023) 2023
Steps
Concepts
Step 1: Identify the diameter of the circle, which is given as 16 cm.
Step 2: Calculate the radius by dividing the diameter by 2. So, radius = 16 cm / 2 = 8 cm.
Step 3: Use the formula for the area of a circle, which is Area = πr².
Step 4: Substitute the radius into the formula. So, Area = π(8 cm)².
Step 5: Calculate (8 cm)², which is 64 cm².
Step 6: Multiply by π to find the area. So, Area = 64π cm².
