The director circle of a circle with radius r is a concentric circle with radius r*sqrt(2).
Circumference of a circle with radius 'r' = 2(PI)(r) ~ 6.28(r)
The radius of a circle is half the diameter so if the radius of a circle is r, then the diameter is 2r.
An annulus. Area = pi (R2 - r2) when R is radius of larger circle and r is radius of smaller circle.
the radius of a circle is r
The director circle of a circle with radius r is a concentric circle with radius r*sqrt(2).
The area of the circle becomes 9 times the area of the original circle. Original circle = Pi * (r ^ 2) = Pi * r * r New Circle = Pi * ((3 * r) ^ 2) = Pi * 9 * r * r

Circumference of a circle with radius 'r' = 2(PI)(r) ~ 6.28(r)
The radius of a circle is half the diameter so if the radius of a circle is r, then the diameter is 2r.
R = Radius The radius is half the diameter of a circle.
Area of a circle is calculated by A=2*p*r where A represents the circle's area and r is the radius of the circle.
Area of a circle = pi R2 'R' is the length of the radius of the circle. That's the distance from the center of the circle to any point on the circle.
R = radius of big circle, r = radius of little circle Area of circle = pi x R x R = 4 x pi x r x r = 4 x pi x 3 x 3 Therefore R x R = 36 and so R = 6 inches
Area of a circle= (22/7)*r^2 where, r is the radius of the circle when r=15, area of the circle= 3.14*15*15 = 706.5 sq.units

An annulus. Area = pi (R2 - r2) when R is radius of larger circle and r is radius of smaller circle.
