Question

A square field is grazed by 4 cows teethered to the 4 corners by ropes of lenth 3. The size of the field is 10. What is the area grazed? ( A ) 56.4 ( B ) 30.3 ( C ) 28.3 ( D ) 100

Answer 1

Step-by-step explanation:

area grazed = area of sector

all cows are at corners so, theta=90

(90/360)×π×9=9π/4

all four cows will graze together =9π
