The circumference of the target above is 5,871.8 mm. What is the diameter of the target? (Use 3.14 for .) A. 3,740 mm B. 467.5 mm C. 1,870 mm D. 935 mm

C. 1870 mm.

Step-by-step explanation:

5871.8 x 3.14 = 1870

C

Step-by-step explanation:

The circumference of a circle can be found using:

We know that the circumference, or c is 5,871.8 We also know the pi is being rounded to 3.14, so we can substitute them in.

5,871.8=3.14d

We want to solve for d. To do this, we need to get d by itself. d is being multiplied by 3.14. To reverse this, divide both sides by 3.14

5,871.8/3.14=3.14d/3.14

The 3.14s on the right will cancel, leaving us with

1870=d

So, the diameter is 1870 mm, or choice C
