To find the radius of a circle with a circumference of 16 kilometers, you can use the formula for the circumference, which is ( C = 2\pi r ). Rearranging this formula to solve for the radius ( r ) gives ( r = \frac{C}{2\pi} ). Substituting in the circumference: ( r = \frac{16}{2\pi} \approx \frac{8}{\pi} \approx 2.55 ) kilometers. Thus, the radius is approximately 2.55 kilometers.
If the circle's radius is 2.5 kilometers, then its diameter is exactly 5.0 kilometers, with no rounding required.
A circle with a radius of 16 inches has a circumference of 100.53 inches.
Radius of circle: 16/2 = 8 inches
radius = 16/(2*pi)
Radius = 16/2 = 8 inches
If the circle's radius is 2.5 kilometers, then its diameter is exactly 5.0 kilometers, with no rounding required.
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
radius = diameter/2
radius = 16/(2*pi)
the circumference of any circle is 2PIr or two times PI(3.14) times the radius (in this case, 16). do the math.
If that equals 16 then the radius is 4
Radius = 16/2 = 8 inches
Area = pi*16*16 square units
Circle with a radius of 8 feet equals a circle with a diameter of 16 feet.
Radius = 16/2 = 8 inches
