A living room has a circular rug. According to a small tag, the rug has a circumference of 6.28 yards. What is the rug's area?
1 answer:
Answer:
A = 3.14 yd^2
Step-by-step explanation:
The circumference is given by
C = 2 * pi * r
Letting pi be approximated by 3.14
6.28 = 2 * (3.14) *r
6.28 = 6.28 r
Divide each side by 6.28
6.28/6.28 = 6.28r/6.28
1=r
We can find the area by
A = pi r^2
A = 3.14 (1)^2
A = 3.14
