3x^2 + 3y^2 = 75
Divide both sides by '3'
Hence
x^2 + y^2 = 25
x^2 + y^2 = 5^2
In the Pythagorean Geometry
The circle equation is
x^32 + y^2 = r^2
Hence 5^2 = r^2
Hence r = 5 (The radius)
3x² + 3y² = 75
The radius and diameter of a circle whose circumference is 25.12 are:r = 4d = 8
The radius of a circle whose circumference is 36 pi (113.1) is: 18 (circumference divided by Pi divided by 2 = radius)
The radius
A circle with a radius of 21 meters has a circumference of 131.95 meters.
radius
I think you have missed out an equals sign. If you mean x2 + y2 = 16, then the radius is 4.
I think you have missed out an equals sign. If you mean x2 + y2 = 16, then the radius is 4.
If that means = 36 then then the radius of the circle is 6 units
x2 + y2 = 2
The equation of circle is (x−h)^2+(y−k)^2 = r^2, where h,k is the center of circle and r is the radius of circle. so, according to question center is origin and radius is 10, therefore, equation of circle is x^2 + y^2 = 100
x2 + y2 = r2, where r is the radius.
It is x2 + y2 = 4
(x-0)² + (y-0)² = r²
x2 + y2 = 49
The area of a circle is equal to that of a triangle whose base has the length of the circle's circumference (distance around the circle) and whose height equals the circle's radius which comes to Pi multiplied by the radius squared. Area of Triangle 1/2 *base*height
sqrt(8) = 2*sqrt(2) = 2.83
General formula for a circle is X squared + Y squared = radius squared. So the answer would be x squared + y squared = 2.64575131 squared
