divide by pi which is 3.1415927 and on and on
The radius(radii is the plural) of the circle is half the distance of circle's diameter. The formula is r=(1/2)diameter.
Take the circumference of a circle and divide it by the diameter of that circle: ∏=C/D
in place of r (radius) write d/2 where d is diameter
Area is 4.6 m2
You have answered this question for yourself; the answer is '10' Do you mean to ask ; What is the circumference/area of a circle, with a diameter of '10'?. If so , commit to memory ' elementary school maths. A = pi r^2 C = 2 pi r or pi d . From this 2r = d Hence 2r = 10 r = 5 C = 10 pi = 31.41592.... units A = pi 5^2 = 25 pi = 78.5398... units^2
The circumference of a circle is (diameter) multiplied by (pi).
By multiplying the diameter by pi, since the circumference of a circle is 3.14 times the diameter.
If you know the diameter of the circle, multiply that by Pi (about 3.1416). The result is the circumference.
Circumfrence = pi * diameter It can be experimentally derived very easily.
You multiply the diameter by pi, (Approximately 3.14159), so C=pi D.
the formula to find the circumference of a circle is pi times the diameter. So basically take the diameter and multiply it by 3.14 and that's the circumference.
pi times diameter
It depends on what information you have: radius, diameter, lengths of tangents from a point outside the circle, length of chord and its distance from the centre, etc. Also, the term is circumference, not circumfrence.
Circumference of a circle = pi*diameter Circumference = 50.26548246 or 50 to the nearest inch
Pi x the diameter of the circle will hive you the circumference. The diameter is double the radius so the answer to your question is pi2r.
The formula is circumference= pi times diameter. pi=3.1415926.
Circumference = pi*diameter = 21.99 inches, approx.
