There's a conference of a circle is 20 pie. What is the area of the circle?

Given the circumference of circle = 20π

We know the formula for circumference of circle = 2π·r

So 2π·r = 20π

r = 10 units

Now formula for area of circle is given by : -

Area of circle = π·r²

Area = π·10² = 100π

So, Area of circle = 100π squared units is the final answer.
