A 3 centimeter diameter circle has an area of 7.068 cm2
The diameter is six cm.
Area = π x R2Area = (3.14) x (3cm)2Area = (3.14) x (9cm)Area = 28.26 cm2
The diameter of any circle is twice the radius. Since the radius of this circle is 15mm, the diameter is 15mm*2=30mm. 30mm is also 3cm.
(3cm)2 x pi = 28.274 cm2
A 3 centimeter diameter circle has an area of 7.068 cm2
The perimeter of a circle is its circumference and it is: 2*pi*radius or pi*diameter
The diameter is six cm.
Area = π x R2Area = (3.14) x (3cm)2Area = (3.14) x (9cm)Area = 28.26 cm2
The circumference of a circle can be calculated using the formula C = πd, where C is the circumference, π is a constant approximately equal to 3.14159, and d is the diameter of the circle. In this case, if the diameter is 3cm, then the circumference would be C = π(3) = 3π cm, or approximately 9.42477 cm.

A = 28.27cm2
Using 3.14 as Pi the area of circle is: 0
Using 3.14 as Pi the area of circle is: 28.259999999999998
(3cm)2 x pi = 28.274 cm2
The diameter of any circle is twice the radius. Since the radius of this circle is 15mm, the diameter is 15mm*2=30mm. 30mm is also 3cm.
The area of a 3 cm circle is: 7.069 square cm
