The formula to find the surface area of a circle is: pi x radius², so if we square the radius the answer would be 25, then we multiply that by 3.14 and the answer would be around 78.5, so the answer is 78.5.
The pythagorean theorem states that a^2+ b^2=c^2.
Final answer: None of the above

C2 + a2 +2 = b
Would be the new formula
