Question

A field is in shape of equilateral triangle in which the length of each side is 70m.A cow is tethered at one of its vertices by a 5m long rope.Find the area of the region in which cow can graze

Answer 1

Answer:

13.09m^2

Step-by-step explanation:

length of robe r = 5m

each angle of equilateral triangle = 60°

here cow is tethered at only one of its vertices so area cow can graze

= 60°/360° * πr^2

= 1/6 π(5)^2 = 25/6 × 22/7

= 13.09m^2
