A circle with a radius of 3 cm has an area of 28.27 square cm.
A≈28.27cm2
A circle with a radius of 6 cm has an area that is about 113.1 cm. 3/4 of that is 84.825 cm
The area of a circle can be calculated using the formula A = πr^2, where r is the radius of the circle. Since the diameter is twice the length of the radius, the radius of a circle with a diameter of 6 cm is 3 cm. Plugging this value into the formula, we get A = π(3)^2 = 9π cm^2. Therefore, the area of a circle with a diameter of 6 cm is 9π square centimeters.
