Area of sector calculator

Sure! Here are the steps to find the area of a sector using a calculator:

  1. Measure the radius of the circle.
  2. Measure the angle of the sector in degrees.
  3. Use the following formula to calculate the area of the sector:Area = (angle / 360) x π x radius^2

    where π (pi) is a constant equal to approximately 3.14159.

  4. Input the values of the radius and angle into the calculator.
  5. Multiply the result by π and then divide by 360.
  6. The result will be the area of the sector in square units.

Here’s an example: if the radius of the circle is 5 cm and the angle of the sector is 60 degrees, the formula would be:

Area = (60 / 360) x π x 5^2

Using a calculator, we get:

Area = (0.1666667) x π x 25 Area = 4.145 radians (rounded to 3 decimal places)

So the area of the sector is approximately 4.145 square cm.
