The correct answer is 20.0
13.2 percent (rounded to 1dp).
Circumference of a circle is equal to pi*diameter, or 2*pi*radius, so if d=17.4cm, c=54.7cm (to 1dp), if r=17.4cm, c=109.3cm (to 1dp).
The radius is 3.45
It is: 276.3 because 0.02 is less than 0.05
8.91 to one decimal place (1dp) is 8.9. This is achieved by rounding the number to the nearest tenth, which involves looking at the second decimal place. Since the second decimal place is 1 (which is less than 5), we round down.
