Remember the circle eq'n ;-
C = 2 pi r
Hence
When r = 21
C = 2* 3.14 * 21 =
C = 131.88 units.

What is the circumference of a r equals 2 cm circle?
Circumference = 2*pi*r = 12.566 cm (approx)
What is the circumference of a circle with a diameter of 58.4 cm?
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)
What is the approximate circumference of circle r?
Circumference of a circle with radius 'r' = 2(PI)(r) ~ 6.28(r)
Is c equals 2πr the same as c equals πr squared?
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).
What does the circumference of a circle?
You mean what Is the circumference of a circle? pi*(r)squared.
What is the radius of a circle if its circumference is 42π?
Circumference = 2Ï€r = 42Ï€ so r = 21 units.
What is the circumference of a r equals 2 cm circle?
Circumference = 2*pi*r = 12.566 cm (approx)
What is C equals R times 2 times Pi?
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
What is the circumference of a circle and how do you find it?
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...
What is the circumference of a circle with a diameter of 58.4 cm?
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)
What is the approximate circumference of circle r?
Circumference of a circle with radius 'r' = 2(PI)(r) ~ 6.28(r)
How do you find the circumfirence of a circle?
The circumference of a circle is the distance all around the edge of the circle. To find the circumference of a circle, you use the formula C equals 2 times pi times r, where pi is equal to 22 over 7 and r is the radius.
Is c equals 2πr the same as c equals πr squared?
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).
Formula of r form c equals 2pi r?
The circumference of a circle C is 2Pixr So solving for r we have C/2Pi=r
What does the circumference of a circle?
You mean what Is the circumference of a circle? pi*(r)squared.
What is circumference of the circle d equals 6ft?
Circumference = r x pi and d = 2r. So, r = d/2 = 6/2 = 3ft and Circumference = 3ft x 3.14 = 9.42.
What is the circumference of a circle if the radius is 3 inches?
The circumference of a circle is 2*pi*r. With r = 3, the circumference is 6 pi.
