4
If that equals 16 then the radius is 4
x2 +y2 = R2 =16 = radius 2 R = 4
I think you have missed out an equals sign. If you mean x2 + y2 = 16, then the radius is 4.
Circle with a radius of 8 feet equals a circle with a diameter of 16 feet.
You are describing a circle, with its center at the origin and a radius of 4 (the square root of 16)
4
(x+7)2+(y+5)2 = 16 Centre of circle: (-7, -5) Radius: 4
I think you have missed out an equals sign. If you mean x2 + y2 = 16, then the radius is 4.
If a circle has a circumference of 16 cm then the radius is about: 2.546 cm
A circle with a radius of 16 inches has a circumference of 100.53 inches.
Radius of circle: 16/2 = 8 inches
The length of an arc on a circle of radius 16, with an arc angle of 60 degrees is about 16.8.The circumference of the circle is 2 pi r, or about 100.5. 60 degrees of a circle is one sixth of the circle, so the arc is one sixth of 100.5, or 16.8.
