Area = 22/7 * r2
Area = pi*r2 where pi CAN be approximated by 22/7 but more accurate values of pi are available.
The area of a circle of radius r is pi*r*r
Area of a circle= (22/7)*r^2 where, r is the radius of the circle when r=15, area of the circle= 3.14*15*15 = 706.5 sq.units
The formula to get the area of a circle ("R" being the radius of the circle). Radius means the distance from the center of the circle to the edge.It means pi times radius squared which is the formula for finding the area of a circle.
50.24=pi(r^2) 15.9918887=r^2 the radius is 3.99898596
For a circle Area is defined as: A = π(r)2 Where "A" is the area, "r" is your radius and π = 3.14 So for your circle: A = 3.14 x (15)2
Ï€*r2, where r is the radius of the circle.
For a circle or radius r, the area is given by: area = {pi}r2 (ie pi times the radius squared)
The Area of a circle is Pi (r)(r) so the area of a circle with the radius of 4, would be 16pi
A circle of radius r has an area of Pi*r*r, where Pi is the constant which is approximately 3.14159.
The area of a circle of radius r is pi*r*r
Area of a circle= (22/7)*r^2 where, r is the radius of the circle when r=15, area of the circle= 3.14*15*15 = 706.5 sq.units
A= Area of the circle¶= Pi (About 3.14)r= Radius squared (Radius times radius)3.14 * Radius squared
The formula to get the area of a circle ("R" being the radius of the circle). Radius means the distance from the center of the circle to the edge.It means pi times radius squared which is the formula for finding the area of a circle.
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.
The area of a circle is pi * r2 where r is the radius Solving for r, where A is the area: A = pi * r2 A/pi = r2 r = sqrt(A/pi)
Circle area = (Pai) r 2 where r is the radius. Area = 3.14 x 23 x 23 = 1661.06
The area of a circle is calculate as:A = pi x r squared If the radius "r" is in feet, the area will be in square feet.
