If a circle has a diameter of (x+3) inches, what is its circumference? A. (x (Pi) + 3 (Pi)) inches

B. (2x (Pi) + 6 (pi)) inches

C. (x+3) (pi) inches/2

D. (xsquared+6x+9) inches

Answer: Option A.

Step-by-step explanation:

diameter (d) = radius (r) * 2

r = d / 2

r = (x + 3) / 2

Now,

Circumference = 2 * π * r

Circumference = 2 * π * (x + 3) / 2

Circumference = π * (x + 3)

Circumference = xπ + 3π inches
