How do i find the radius of a circle when the circumference is 11.32?

Question

i'm trying to do homework and i'm trying to find the radius and the area of a circle and it's circumference is 11.32. please help. . .thank you very much!

Answer 1

r = C/2(pi)

r = 11.32/ 6.2832

r = 1.802

Not a GEOGRAPHY question.

Answer 2

the formula is...

11.32 divided by 3.14

Answer 3

circumfrence = 2 x pie x radius

so 11.32 = 2x(22/7) x r

solve.. instead of 22/7 u can find pie in the calc.

oh and the area is  pie x radius-squared

after u find the radius find the area. remember the answer is in unit squared

Answer 4

The circumference of a circle is the product of the diameter and the number Pi.

Circumference = Pi * Diameter

The Diameter is twice the Radius.

Diameter = 2 * Radius.

Circumference = Pi * 2 * Radius

Therefore:

Radius = Circumference / (Pi * 2)

Answer 5

Here you go very easy

C= 2 x p ix r.Solove it for r

r= c/2pi

r= 11.32/ 2 x 3.14

hope you can do the rest is just a matter of division and multipication. Note the value of Pi is constant and always 3.14 or  22/7

Answer 6

JUST DIVIDE BY 2 AND IT'S 5.66.
