Answer: d, the diameter, is about 36.92 units
Step-by-step explanation:
The c value is the circumference and we are being asked to solve for the diameter.
We can take the value they give for the circumference, plug it into the circumference formula, and solve for d. Please note that the diameter is two times the radius, or r, so at the end I will multiply r by two.
C = 2πr
(116) = 2πr
18.46 ≈ r
r ≈ 18.46
-
18.46 * 2 = 36.92
The missing measure is about 36.92 units.
