37.7 centimeters.
I just took that test. ;)
A circle has the radius of 27.7 cm what is the approximate circumference of the circle? The circumference is approx. 174 centimeters.
Circumference of the circle is 2*pi*10 = about 63 cm rounded up.
A circle with a radius of 2.8 centimeters has a circumference of 17.59 centimeters.
In a semicircle, the diameter is the straight line. It is also equal to double the radius, and that property allows it to be used when calculating area and circumference.
If radius of a circle is 9 centimeters the circumference would be: 56.55 cm (r x 2 x Pi = circumference).
You can multiply the radius by pi to get the length of the semicircle.

A circle with a radius of 15.5 centimeters has a circumference of 97.39 centimeters.
2pi sq cm
The radius is 7cm

The wheel's circumference is: 219.9 centimeters.
If radius of a circle is 9 centimeters the circumference would be: 56.55 cm (r x 2 x Pi = circumference).
