Question
The diameter of a circle is 8 centimeters. What is the area of the circle?
Solution
Sure, here are the steps to find the area of the circle:
Step 1: Understand the formula for the area of a circle, which is A = πr², where r is the radius of the circle.
Step 2: Given that the diameter of the circle is 8 cm, the radius would be half of the diameter, which is 4 cm.
Step 3: Substitute the radius into the formula: A = π(4 cm)².
Step 4: Calculate the area: A = π(16 cm²) = 50.27 cm².
So, the area of the circle is approximately 50.27 square centimeters.
