The correct answer is 20.0
To round 76.4491 to one decimal place (1dp), you look at the second decimal place, which is 4. Since 4 is less than 5, you keep the first decimal place as it is. Therefore, 76.4491 rounded to one decimal place is 76.4.
4.962 rounded to one decimal place (1dp) is 5.0. This is because when rounding, you look at the digit in the second decimal place (which is 6) and since it is 5 or greater, you round up the first decimal place from 9 to 10, resulting in 5.0.
It is: 21.2

It depends what number you're rounding to. (dp=decimal place) 0.7234 (4dp) 0.723 (3dp) 0.72 (2dp) 0.7 (1dp) 1 (1sf (significant figure))
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
