Question

The area of a circular Garden is 5544 m^2. outside this Garden, a path of uniform width is a laid all around the area of the path is2002 m^2. find
a) the radius of the circular Garden .
b) the width of the path.

Answer 1

We know that area of circle is ( pi × radius square)
So if the radius if the garden is "r"
then
22/7 × r^2 = 5544 ( since pi= 22/7)
r^2 = 5544 × 7 /22
r^2 = 1764
r = root over 1764 = 42m
