The area of a circle's formula is pi (3.14) r squared.
The radius is half the diameter, so 1.5.
7.065 is the answer.

circumference = pi*18 cm area = pi*92 square cm
It is 14.00281721 or about 14 cm
A circle with a diameter of 8.5 cm has an area of 56.75 square cm
The area of a circle that has diameter of 3 cm is: 7.069 cm2
The area of a circle whose diameter is 10 cm is: 78.54 cm2
The circumference of a circle whose area is 16 times the area of a circle whose diameter is 1.4m is: 17.6 cm
78.54 square cm

circumference = pi*18 cm area = pi*92 square cm
It is 14.00281721 or about 14 cm
Area = 12.6 cm2Circumference = 12.6 cm
The area of a circle with a diameter of two cm is about 3.1416 cm.
A circle with a diameter of 8.5 cm has an area of 56.75 square cm
The diameter of a circle with an area of 86.54625 cm2 is: 10.49734 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.
The area of a circle that has diameter of 3 cm is: 7.069 cm2
