4 to the second power is 16 and pie is always 3.14 so pie times radius so multiply 3.14 and 16 and that is your answer 50.24 answer
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)

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 = 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.
The area of a circle with radius 5 is 25 pi. Concentric circles with radius 3 and 4 have areas of 9 pi and 16 pi. The concentric circle with radius four consumes the circle with radius 3. 25 pi minus 16 pi leaves 9 pi of the circle with radius 5 left over. 16 pi is slightly over three-fifths of the circle with radius 5.
