If the radius is 6 units, the diameter is 12. To find the circumference, you multiply the diameter by pi to get 12pi or 37.699, which rounds up to 37.70.
if you mean a radius of 5 units then the answer is 78.54 APEX
28.27
Circumference of circle: 2*pi*3.5 = 22cm rounded to the nearest whole number
Its radius is 4.8 cm, rounded to the nearest tenth.
Circumference of circle: 2*pi*35 = 220 cm rounded to the nearest whole number
To the nearest hundredth, the circumference of a circle with a radius of 4 is 25.13
A circle with a radius of 5 units has a circumference of 31.42 units.
37.69
43.98 units
r = 0.95
138.23
A circle with a radius of 4 units has a circumference of 25.13 units.
0.95 - 0.96 units
47.25
Circumf. divided by 2Pi = radius 244.92 / 2Pi = 38.98 radius (to nearest hundredth).
If you have the radius, then area = pi*r2 which you then round to the nearest hundredth. If you do not know the radius but do know the diameter or circumference, you can calculate the radius. Otherwise you need to measure it.
16.6 x pi = 52.15 to the nearest hundredth
