Question

Circle P has a circumference of approximately 75 inches.

Circle P with radius r is shown.

What is the approximate length of the radius, r? Use 3.14 for . Round to the nearest inch

Answer 1

Answer: The radius it 11.94 (Rounded to the nearest hundredth)

Explanation:

We know that the formula for finding circumference is the following:

C = 2rπ

Because we already know that the circumference of circle P equals to 75 inches, we most substitute this for "C" to find the radius, "R".

(75)=2rπ Now get the variable "R", the radius, by itself.

75/2π = 2rπ/2π Instead of using π, this question tell us to use 3.14

75/2(3.14) = 2r(3.14)/2(3.14)

75/6.28= 2r(3.14)/6.28

Radius =11.94, rounded to the nearest hundredth

Answer 2

1) 12in

Step-by-step explanation:

The circumference is 75, so to find the diameter you have to divide 75 by 3.14. You get 24 approximately. Then divide the diameter by 2, so 24/2=12.
