Area of Circles - JSS3 Mathematics Lesson Note
The area of a circle is given by the formula:
Area=𝜋×radius^2
For instance:
Take a circle with a radius of 5 units.
Area=m 𝜋×5^2=25𝜋 square units
If you need a numerical approximation:
Area≈25×3.14=78.5 square units (approx.)
Therefore, the area of this circle is approximately 78.5 square units.
