Circumference = 2*pi*r = 12.566 cm (approx)
A circle with a radius of 21 units has a circumference of 131.95 units.

9. Circumference equals 2 times Pi times the radius. C=2(pi)r. "r" for radius. So if your circumference is 18 times pi, then you do 18 divided by 2, which gives you a radius of 9.
circumference = 2*pi*6 = 37.699 inches to 3 decimal places
The circumference is Pi x r x r.... In THIS case it's .25 x .25 x Pi... which equals 0.19634375
Circumference = r x pi and d = 2r. So, r = d/2 = 6/2 = 3ft and Circumference = 3ft x 3.14 = 9.42.
The circumference of a circle is its perimeter, or the distance around it. It equals 2(pi)r or pi*d, where r is the radius, d is the diameter and pi is 3.14...
The circumference of a circle C is 2Pixr So solving for r we have C/2Pi=r
Circumference = 2*pi*r Circumference = 2*3.14*25 => 157 inches
Circumference is pi times diameter. If the radius is 24, the diameter (twice the radius) is 48, making the circumference 48pi, or approximately 150.72 units.
C = 2 pi r = 6.40 pi = 20.1062 inches (rounded)
(20 X 20) X 3.14 = 1256 yards Pi = 3.14 Circumference = 1256yd
The circumference of a circle is 2πr where r is the radius or πd where d is the diameter. The circumference of the apple pie divided by its diameter is πd/d = π.
C = pi*r82 C = Pi*r*2 90=R Thus 180*Pi
0.32 equals 320 thousands.
No. C = 2*pi*r is the equation representing the circumference of a circle. The area of a circle is equal to pi*(r^2).
The circumference of a circle. This is the total amount of length around the circle. C= Circumference R= radius of the circle Pi=3.14159
r = c/2pi (radius of a circle equals the circumference divided by (2 x pi)
The circumference of a circle is 2 * r * pi or d * pi; the diameter "d" = 2* the radius "r". "pi" is - VERY approximately! - 3.14. The area of a circle is pi * r^2. There is a calculator built into Windows, or you can use the calculator built into Google.
the circumference of a circle equals 2x(pi)x(r) r=d/2 r=58.4/2=29.2 the answer =2x(pi)x29.2 =58.4(pi)
C = 2,010.62
