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
(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.
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.
circumference = pi x diameter = 3.1416 x 3cm = 9.42cm (approx)
Area = π x R2Area = (3.14) x (3cm)2Area = (3.14) x (9cm)Area = 28.26 cm2
29.76
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
