Question
What is the approximate area of the circle. the diameter is 18 cm
Answers
GPT 3.5
The radius of the circle is half of the diameter, so the radius is 9 cm.
The area of a circle is calculated using the formula A = πr^2, where r is the radius.
Plugging in the values, we get:
A = π * 9^2
A = π * 81
A ≈ 254.47 square centimeters
So, the approximate area of the circle with a diameter of 18 cm is 254.47 square centimeters.
