Question

18. A cow is tied to a pole, fixed at the midpoint
of a side of a square field of dimensions
40 m * 40 m, by means of 14 m long rope.
Find the area that the cow can graze.
Options 245
B 254
C 308
D 380​

Answer 1

Answer:

246 is the right option but I am not sure sorry for this

Answer 2

Step-by-step explanation:

area of a semi circle=1/2 πr²,

then radius of the circle(or the length of the rope by which the cow has been tied)= 14 cm,

then the area of grass the cow can graze =1/2 π r²,

=

$\frac{1}{2} \times \frac{22}{7} \times 14 \times 14 \\ = 44 \times 7 \\ = 308 {cm}^{2}$

NOW, THE CORRECT ANSWER IS 308 CM².
