Well first you find on your calculator you need to find pi which looks something like this π.
Now to find the curcumference of any circle the formula is pi multiplied by the diameter.
The radius is 16 metres, and the diameter of any circle in life is two multiplied by the radius.
So you do π times by 32 which equals 100.53(I rounded it off to the nearest 2 decimal places).
or even easier
3.14 x radius 2

PI times raduis 2
and now for area
2 times 3.14 times raduis

A circle has a radius of 16 what is the area of the circle?
Area = pi*16*16 square units
What is the diameter of a circle when the radius is 8?
Diameter = double the radius = 16
What is the radius of a circle if the diameter is 16 inches?
The radius of a circle is half of the diameter. Therefore, if the diameter is 16 inches, the radius would be half of 16, which is 8 inches. The radius is the distance from the center of the circle to any point on the circle's circumference.
Radius of circle is 16 inches how long is diameter?
32"
If the radius of a circle is 8 what is the diameter?
If the radius of a circle is 8, then the diameter is 16. The diameter of a circle is two times of a radius The equation would be d = 2r so plugging in 8 for r, the equation would become d = 2(8) Therefore d is 16.
