Question

A goat is tied to one corner of a square plot of side 12m by a rope 7m long.Find the area it can graze?

Answer 1

we will first take the area of circle whose radius is the length of the rope
Area of the circle =πr^2
=22/7×7×7=22×7=154m
now we will divide it by 4 as it is tied in a square plot
154÷4=38.5m^2
