Area of a circle = pi*radius squared

the formula for the area of a circle is 3.14 x radius squared

The formula to find the area of a circle is: A = pi * r2

area of a circle = pi*r2

The area of a circle can be found with the formula (pi)r^2

Area formula for circle= --,,- r 2

The formula to find the area of a circle is pi x the radius squared.

Area of a circle = (Pi)(Radius)2

Area of a circle = pi*radius2

Area of any circle = pi*radius squared

The formula for the area of a circle is: Area = (pi) x (Radius)2 . When you know the radius of the circle and you use it to calculate the area of the circle, the result will be equal to (pi) x (Radius)2 .

There is no specific formula for a sector of a circle. There is a formula for its angle (at the centre), its perimeter, its area.

The formula for the area of a circle is pi * radius squared. The circumference of a circle's formula is pi * diameter. NOTE: pi equals approx. 3.14

In order to convert the area of a circle to the circumference of the circle, divide by the radius and multiply by two. The formula for the circumference of a circle is pi times the diameter.

the formula to calculate the circumference of a circle is the diameter of the circle x 3.14 or "pie"

That depends what kind of figure you are talking about. The formula for the area of a circle is quite different from the area of a rectangle, for example.That depends what kind of figure you are talking about.

Area of a circle = pi*radius2 measured in square units

Area of a circle measured in square units = pi*radius2

Area of a circle = pi*radius2 and measured in square units

Area of a circle = pi*radius squared

The formula for the circumference of a circle is: radius (x) 3.14 (pi) Area is... Radius2 x 3.14

Circumference of a circle is (pi * diameter). Area of a circle is (pi * r2).

The formula for the area of a circle is pi times the radius squared. The formula for the circumference of a circle is two times pi times the radius.

It says so in the formula

semi means half A semi-circle is half a circle The formula for the area of a circle is A = (Π * r^2) Area of semi circle = (Π * r^2) ÷ 2
