Question

what is the surface area of a circle that has a diameter or 14 inches?? FAST PLEASE

Answer 1

Formula:
\(area = π · r2\)

Answer 2

Formula:
\(area = π \times r^2\)
Radius = r
Radius is half of the diameter.
But since we are squaring it. We don't need to divide the diameter in half.
Plug in the numbers:
\(area = 3.14 \times 14\)
Answer:
43.96
