The formula for the circumference (C) of a circle is C = 2π r, where r is the radius.
Therefore, π = C/2r. As the diameter is 2 x radius, then π is the ratio of the circumference of a circle to its diameter.
π is usually presented as a number to eight significant figures (3.1415927)in a standard calculator. As an approximate fraction 22/7 is used where a fine degree of accuracy is not required.
EXAMPLE : r = 5 : C = 2π x 5 = 10π = 31.425927 when a calculator is used or 220/7= 31.4286 when pi = 22/7 is used.

What is the radius of circle that's circumference is 10 feet?
Circumference = 2 x pie x radius Therefore, radius = 10/2/pie =1.6
How will you find the radius if you only have the circumference?
by timesing the circumference by pie
How do you get the radius of the circle with the circumference?
divide the circumference by pie (3.14) and the answer would be the radius. for example circumference = 314 pie = 3.14 so 314 divide by 3.14 = 100 so the radius = 100
What is the radius of a circle with circumference of 2 pie?
radius = 1, C=2(pie)r
What is the circumference of a circle if the radius is 4.4 cm?
Work it out the circumfrance of a circle is pie x the diameter!
Work out the radius of a circle from the circumference?
c=2*pie*r c= circumference r= radius.
How do you find the circumference with radius of 18 in if you leave your answer n pie terms how many inches is it?
Circumference = 2*pi*radius or pi*diameter Circumference = 36pi inches
The radius is about what to the circumference?
The radius is the circumference divided by pie, all divided by two. :)
What is the radius of circle that's circumference is 10 feet?
Circumference = 2 x pie x radius Therefore, radius = 10/2/pie =1.6
How will you find the radius if you only have the circumference?
by timesing the circumference by pie
How do you get the radius of the circle with the circumference?

What is the radius of a circle with circumference of 2 pie?
radius = 1, C=2(pie)r
What is the circumference of a circle if the radius is 4.4 cm?
Work it out the circumfrance of a circle is pie x the diameter!
Circumference of a circle with radius 9 inches?
r2*pie=circumference 9(9)*pie 81*pie 254
What is the circumference of a circle with a 9 inch radius?
(pie)(diameter)=(circumference) (pie)(9)(2)=18(pie)=56.549
How do you get the radius when you are given the circumference?
Let C be the circumference, r be the radius, and (pie)= 3.141592654 C = 2 x (pie)x r r = C ÷ (2 x (pie))
Is the circumference 3 times the radius?
No, the formula for a circumference of a circle is 2(pie)r For example, if r is 6, the the circumference is 12(pie)
