What is the area of 45mm diameter circle?

The area (A) of a circle is A = π . r2 The diameter (D) is equal to D = r / 2 . Were r is the radius. If the diameter of the circle is 45 mm, and we divide it by 2. We will obtain the radius which is equal to 22,5mm: D = 45mm / 2 = 22,5mm If we square this radius the result is 506,25mm2: r2 = (22,5mm)2 = 506,25mm2 So the area of the circle of diameter 45mm is: A = 506,25mm2 . π = 1590,43mm2d
