Question

a cow is tied to a pole fixed to a midpoint of a side of a square field of dimensions 40mx40m, by means of 14m long rope.Find ( I ) the area that the cow can graze ( ll ) the decrease in the grazing area if the length of the rope is 10.5m ​

Answer 1

Answer:

Step-by-step explanation:

the area of the field that the cow can graze

=40×40-π×r×r

=1600-22/7×14×14

=1600-616

=984m

after the length of the rope is reduced

=40×40-3.14×10.5×10.5

=1600-346.185

1253.815
