Hi 3DST3!

The diameter of a circle is x 2 the radius. The radius is, as you checked, 5m. Therefore the answer cannot be A.

The circumference formulas are
\pi * diameter or 2
\pi (3.14 rounded)r. The radius of the circle is 5 and pi (rounded) = 3.14, therefore, 2*3.14*5. 2*3.14*5 = 31.4. Therefore b isn't a correct answer choice and neither is e.

The diameter, as I said, is 2 * r. Our r is 5. 2 * 5 = 10. 10 is our diameter and C the correct answer choice.

The area of a circle's formula is
\pi
r^(2) Therefore 3.14 * 5^2 -> 3.14 * 25 = 78.5. D is correct.

Answers that are correct:
C
D
F

Answers that are incorrect:
A
B
E
