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
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
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)
What is Pi R Squared?
The formula for the area of a circle is πr^2, where π (pi) is a mathematical constant approximately equal to 3.14159, and r is the radius of the circle. So, "pi r squared" refers to the area of a circle, calculated by multiplying π by the square of the radius. This formula is fundamental in geometry and mathematics for finding the area enclosed by a circle.
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
