Calculate the area of a circle whose diameter is 7cm
Answers
GPT 3.5
The radius of a circle is half of its diameter. Therefore, the radius of this circle is 7cm/2 = <<7/2=3.5>>3.5cm.
The area of a circle can be calculated using the formula A = πr^2, where A represents the area and r represents the radius.
Substituting the values, we have A = π(3.5)^2 = π(12.25) ≈ 38.484 cm².
Therefore, the area of the circle is approximately 38.484 square centimeters.
