How do you find the circumference of a circle? The only information given is that the radius is 6.
The formula for the circumference of a circle is C = ПD (circumference = pi times the diameter). The diameter is two times the radius. Therefore, if you have the radius, C = 2 ПR (twice the radius, times pi).
If the radius is 6, the circumference is 12 П.
The formula for circumference of the circle is pi*d or 2*pi*r, where:
d= diameter, r= radius, pi= π
The circumference can be
pi *diameter or 2*(diameter/2( which is the radius))*pi, simplified to be (2*r*pi)
The circumference of a circle can be derived from its radius r by using the formula C = 2*pi*r
For a circle with radius 6, the circumference is obtained by substituting r = 6 in the formula given earlier.
C = 2*pi*6 = 12*pi
The circumference of the circle is exactly 12*pi or approximately 37.69
The formula for circumference of the circle is pi*d or 2*pi*r Where pi= 3.14
since the radius is given you would do 6*3.14*2
What do we know
- FORMULA FOR CIRCUMFERENCE: C=`2pir=2pid`
In this case we should use C=`2pir`
Plug in r=6 & replace `pi` with 3.14
2*pi*r is the equation for the circumference pi is 3.14 and you said radius is 6
so the answer is 37.68
The formula for the circumference of a circle is `2xxpixxr` .
We know the radius so we can get an answer easily.
This is the answer in terms of pi. pi is a mathematical constant equal to 3.14....(a never ending decimal).
just plug it into these formulas (pi x d ) d= diameter which is (2 x radius)
2r x pi
pi = 3.14
C = 2 ПR
2(3.14)(6) or 2(П)(6)
circumference = 37.68 or 12П
