Question

There is a circular fieldnof area ofbappoximatepy 500 m2 how can you find it's area accurately byvising a measuring tape

Answer 1

Explanation:

By using a rope of measurable length, we can measure the perimeter of the field.

This perimeter in terms of rope length can be measured accuratley with the help of measuring tape, by measuring the length of the rope.

Once perimeter is found accuratley, we can calculate the redius of the field, using formula

Perimeter of circle = 2π r

After calculating the redius, area of the field can be calcuated as,

Area of the circular section = π r²
