Area = π*d2 / 4
d = 30 cm => area = 706.86 sq cm
60cm
Diameter = 30cm so radius = 15 cm. Then Area = pi*r2 = 706.9 cm2
30/pi cm
d = 9.55 cm
The diameter of a circle is the distance across it, passing through the center. If the diameter is 30 cm, that means the full width of the circle from one edge to the opposite edge is 30 cm. Therefore, the diameter is simply 30 cm.

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
The diameter of a circle is the distance across it, passing through the center. If the diameter is 30 cm, that means the full width of the circle from one edge to the opposite edge is 30 cm. Therefore, the diameter is simply 30 cm.
To find area of a circle using diameter, you use this formuler. Area=pi(diameter/2)(diameter/2)
