Well, darling, if the diameter of a circle is 16cm, then the radius would be half of that, which is 8cm. To find the area of a circle, you use the formula A = πr^2, so plug in 8 for the radius and you get an area of 64π square centimeters. So, there you have it, sweet cheeks, the area of the circle is 64π square centimeters.
64 pi sqcm
16cm
256 pi cm2
The diameter is twice the radius and so 2 times 16 = 32cm
The area of a circle with a diameter of 9.4 m is: 69.4 m2
64 pi sqcm
16cm
The diameter of a circle is the length of a straight line from a point on the edge of the circle passing through the center of the circle and onto a point on the opposite edge of the circle. The radius of a circle is the length of a straight line from the center of a circle to a point on the edge of the edge of the circle. So the radius of a circle is half its diameter, in this case 8cm.
256 pi cm2
A = pi x 8(sup)2 cm(sup)2; C = pi x 16 cm
pi*d =22*16/7 =50.2857 cm
64 pi ie just over 201 sq cm
The diameter is twice the radius and so 2 times 16 = 32cm
The diameter of a circle with an area of 37.68 is 6.92
The area of a circle with the diameter of 3m is 7.069 m2
The area of a circle with diameter of 4.9 is 75.43 units2
To find area of a circle using diameter, you use this formuler. Area=pi(diameter/2)(diameter/2)
