The answer depends on what the number 0.45 refers to: radius, diameter or area?
3.74
11.70
Well, isn't that a happy little question! To find 84.099 to the nearest hundredth, we look at the second decimal place. Since the number after the hundredth place is 9, we round up to 84.10. And just like that, we've created a lovely rounded number that is easy on the eyes!
The square root of 4 is 2
The circumference of a circle with radius of 7 km is 44.0 km (to the nearest tenth), and the area of a circle with radius of 7 km is 153.9 km (to the nearest tenth).C = 2 pi RA = pi R2
47.25
If you have the radius, then area = pi*r2 which you then round to the nearest hundredth. If you do not know the radius but do know the diameter or circumference, you can calculate the radius. Otherwise you need to measure it.
The circumference of a circle can be calculated using the formula C = 2πr, where r is the radius. Given the radius as 47, the circumference would be C = 2 * 3.14 * 47 = 294.04. Rounding to the nearest hundredth, the circumference is approximately 294.04 units.
You find the hundredth place then look at the number behind it. If its greater than 5, round up. If not, round down
16.6 x pi = 52.15 to the nearest hundredth
Round your answer to two decimal places. Example: Your calculator's answer is 2.133334442 You round to: 2.13
Circumference of a circle = 2*pi*radius or pi*diameter Circumference = 21.67698931 or 21.7 meters to the nearest tenth
to find the raduis of any circle, divde the diameter by 2. in this case, the answer would be 3.50
21.99
If the radius is 6 units, the diameter is 12. To find the circumference, you multiply the diameter by pi to get 12pi or 37.699, which rounds up to 37.70.
