Question

5. There is a circular field of area of approximately 500 m2. How can you find its area accurately by using a measuring tape?​

Answer 1

Answer:

Answer: By using measuring tape, measure the diameter of the circular field ie from one side of the circular field to the other side. Now divide the diameter by 2 which gives radius of circular field. Now using the formula A=π ×r2A=π ×r2 we can find area of circular field.

Answer 2

A

$a pie \times r \: 2a\pi \times r2$
