Question

Two fences in a field meet at 120 degrees. A cow is tethered at their intersection with a 15-foot rope, as shown in the figure. Over how many square feet may the cow graze?

Answer 1

Area of the field that the cow graze = 235.71 sq. ft

Explanation:

Area of the field that the cow graze = (120 / 360) * πr²

= (1/3) * (22/7) * 15 * 15

= (22 * 5 * 15) / 7 = 1650 /7

= 235.71 sq. ft
