A circle has radius r what is the formula for the area of the circle?
For a circle or radius r, the area is given by: area = {pi}r2 (ie pi times the radius squared)
Area of a circle with .125 radius?
A circle of radius r has an area of Pi*r*r, where Pi is the constant which is approximately 3.14159.
What is the area of a circle when the radius is 23?
Circle area = (Pai) r 2 where r is the radius. Area = 3.14 x 23 x 23 = 1661.06
What is a circle with a little circle in it called?
An annulus. Area = pi (R2 - r2) when R is radius of larger circle and r is radius of smaller circle.
What is the area of a circle whose radius is 6 cm?
The area of a circle with radius r is pi*r*r where pi = 3.1416 approx. When r = 6 cm, the area is 113.1 sq cm.
What is the area of a cirle with a radius of 5 in?
The area of a circle of radius r is pi*r*r
Area of circle with radius of 5?
A=pi times R squared If the radius is 5, the area is 25pi
What is the area of 5 km radius in square km?
An area of 5km radius implies a circle. The area of a circle of radius r is {pi}r2. Area ~= 3.14 x 5 x 5 km2 ~= 78.54 km2.
A circle has radius r what is the formula for the area of the circle?
For a circle or radius r, the area is given by: area = {pi}r2 (ie pi times the radius squared)
What is the Area of circle of radius 4?
The Area of a circle is Pi (r)(r) so the area of a circle with the radius of 4, would be 16pi
Area of a circle with .125 radius?
A circle of radius r has an area of Pi*r*r, where Pi is the constant which is approximately 3.14159.
What is the area of a circle when the radius is 15?
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
How do you get the area of a circle?
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
How you get the area of a circle?
A= Area of the circle¶= Pi (About 3.14)r= Radius squared (Radius times radius)3.14 * Radius squared
What is Pi R 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.
Help with math how do you get 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.
How do you find the radius of a circle if you have area?
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)
