the formula for the area of a circle is pi r2 (pie are square). r is the radius.
examples:
radius of circle is 5. pi 52 = pi 25 = 78.53
Area of a circle = pi*radius2
Area of a circle = Pi * radius2
Area of a circle = pi*radius2
The area of a circle is the amount of space inside the circle. The area of a circle is calculated by multiplying pi(3.14159) by the radius squared.
Area of a circle is calculated by A=2*p*r where A represents the circle's area and r is the radius of the circle.
If the area of one circle is twice that of another, the ratio of the area of the smaller circle to the larger circle is 1:2. To express this as a percentage, the area of the smaller circle is 50% of the area of the larger circle. Thus, the ratio in percent of the smaller circle to the larger circle is 50%.
Using 3.14 as Pi the area of circle is: 0
the area of the circle is increased by 400%
The circle's area is 70,900,000 square units.
Area of any circle = pi*radius2
Area of a sector of a circle.
To find the area of the circle pi*radius*squared and subtract the area of the figure inside
