Answer: 7546feet²
Step-by-step explanation:
Since the pen has 308 feet of fencing, this is the perimeter of the circular pen and we can get the raduus which goes thus:
Circumference of a circle = 2πr
2πr = 308
2 × 22/7 × r = 308
44/7 × r = 308
r = 308 × 7/44
r = 49
Therefore, area of the circular pen will be:
= πr²
= 22/7 × 49 × 49
= 7546feet²
Answer: C. 4
Step-by-step explanation:
First, we can prime factorize 52.
52 = 2^2 * 13
13 is not a square number, but 4 is a square number because it equals 2 squared.
Therefore, the correct answer is C. 4
