Question

The circumference of the target above is 6,261.16 mm. What is the diameter of the target? Use = 3.14.

Answer 1

Hello!

To find the diameter we can use the equation to find the circumference


`C = 2 \pi r`

C is circumference
r is radius

Put in the values we know and 3.14 for pi


`6261.16 = 2 * 3.14 * r`

Multiply


`6261.16 = 6.28 * r`

Divide both sides by 6.28

997 = r

the diameter is double the radius

997 * 2 = 1994

The answer is 1994mm

Hope this helps!
