What is the area of a circle?

Answer 1

A=pi*r^2 Or A=pi*(d/2)^2

The area of a circle is determined by squaring the radius, and multiplying this product by pi (approx. 3.1415926, represented by the symbol 'π'). In common mathematical terms, the area of a circle is represented by the expression π(r^2)

Answer 2

The area of a circle is determined by squaring the radius, and multiplying this product by pi (approx. 3.1415926, represented by the symbol 'π'). In common mathematical terms, the area of a circle is represented by the expression π(r^2)

Answer 3

A=pi r2 (area = pi x radius squared). Pi is approximately 3.1416.

Answer 4

A=pi times r2

r2 = r times r

Answer 5

Pi times the radius squared

Answer 6

area of a circle =pi*radius 2
