Answer:
Step-by-step explanation:
Part A
The area of circle with radius of 2 yd (the length of the rope) is:
- A = π*r² = 3.14*2² = 12.56 yd²
Since 1/4 of the circle is occupied by the shed, the area of the grass is:
Part B
Let the area be 30 yd², finding the r as per above formula:
- 3/4*3.14*r² = 30
- r² = 30*4/3*3.14
- r² = 12.74
- r = √12.74
- r = 3.57 yd
