Formula and result of area of circle?
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 .
When radius is unknown then how to find area of a circle?
By dividing its diameter by 2 is equal to the radius of a circle and its area is pi*radius2
What is the radius of a circle if its circumference and area both equal 246?
A circle cannot have its circumference and area both equal to 246. The only possible equal values are circumference = 12.6 units area = 12.6 square units which are achieved by a circle with radius 2 units.
How does area of a circle relate to circumference?
The area of a circle is equal to the perimeter times half the radius. That is, A = P*r/2
What is the formula of area semicricle?
The area of a semicircle is one-half the area of a circle. it is equal to (pi/2)r^2, where r is the radius.
