Explanation

The diameter of a circle is the distance across the circle through its center. To find the area of a circle, you can use the formula: A = πr^2

Where A is the area of the circle and r is the radius of the circle. The radius of a circle is half of the diameter.

In the case of diameter of 50cm the radius would be: r = 50 cm / 2 = 25 cm

So you can use the formula above to find the area of the circle: A = π * 25^2 = π * 625 cm^2 A = about 1962.5 cm^2

So, the area of a circle with diameter 50 cm is about 1962.5 cm^2.
