9.4
It is: 21.2
14.0
17.2
62.2
8.8
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
Well, darling, 58.69 rounded is 59. Why? Because that little pesky 6 after the decimal point is closer to 10 than 0, so we bump that number up to the next whole digit. So, there you have it, 58.69 rounded is 59.
