i think you take 4 and times it by 3.14
radius = 5 m so circumference = 2*pi*r = 31.4159 m (to 4 dp)
Circumference of a circle is measure with the formula: C = 2*pi*r where C is the Circumference, and r is the radius. Hence, the circumference of a circle with radius 4 m would be: C = 2*pi*4 = 8*pi Rounded to 2 decimal places, this comes to 25.13 m . Hope this Helps.
The radius of a circle with circumference of 63 m is 10.03 m
The radius of a circle with a circumference of 110 m is: 17.507 m
The circumference of a circle with a radius of 3 m is: 18.85 m.
Circumference of a circle = 2*pi*radius or diameter*pi
Its circumference = 2*pi*4 meters
A circle with a radius of 10 m has a circumference of 62.83 m.
4.6m. The circumference is double the radius.
Half the diameter is the radius. Circumference = 300 m gives radius = 47.75 metres (to 2 dp).
Radius = 22/2pi m
A circle with a radius of 2.25 m has a circumference of about 14.137 meters.
