Circumference = pi * 2 * r
C = 3.14 * 2 * 47 = 295.16
The circumference of a circle with a radius of 20ft is: 125.7 feet (radius x 2 x pi = circumference).
113.1 meters.
r = 159.15 m
The circumference of a circle when the diameter is 30 is: 94.25
if you want me to answer this i need to know the shape, or dimensions
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
138.23
43.98 units
r = 0.95
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
