If C (Circumfrence) = 314 m, what is the area?
1 answer:
Answer:
7850 m^2
Step-by-step explanation:
The circumference of a circle is given by
C = 2*pi *r
314 = 2 * 3.14 *r
314 = 6.28 r
Divide each side by 6.28
314/6.28 = 6.28 r/6.28
50 m= r
Now we need to find the area
A = pi * r^2
A = 3.14 *r^2
A = 3.14 (50)^2
= 3.14 (2500)
7850 m^2
