The circumference of a circle is 32 centimeters. Which is closest to the radius?
A.
10.2 centimeters
B.
5.1 centimeters
C.
16 centimeters
D.
5.3 centimeters
Would be 16 cenimeters I believe
What is 32 divided by 3.14? Divide your answer by 2 to find the radius.
C = pi * 2r,
32 = 3.14 * 2r,
r = ?
My teacher said it was b-

To find the radius of a circle given its circumference, you can use the formula C = 2πr, where C is the circumference and r is the radius.
In this case, the circumference is given as 32 centimeters. So, we have the equation 32 = 2πr.
First, divide both sides of the equation by 2π to isolate the variable r:
r = 32 / (2π).
Now, calculate the value of r using a calculator or an estimate for π. Let's use the approximation π ≈ 3.14:
r ≈ 32 / (2 * 3.14) ≈ 5.095.
Looking at the answer choices, the value closest to 5.095 centimeters is 5.1 centimeters, which is option B.

32 ÷ π = 10.191
10.191 ÷ 2 = radius
(π = 3.14)
I'm not giving you the answer, just how to find it =)
