Question

to obtain formula for area of a circle experimentally​

Answer 1

Answer:

The area (A) of a circle of radius r is given by A = πr²

Answer 2

Step-by-step explanation:

1. Measure or record the diameter. Some problems or situations will not provide you with the radius. Instead, you may be given the diameter of a circle.

2. Divide the diameter in half. Remember that the diameter is equal to   double the radius.

3. Use the original formula for area.

4. Report the value of the area. Recall that your area is to be reported in square units.
