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)
