-- Find the volume of a sphere with radius = 1.56
-- Find the volume of a sphere with radius = 1.61
-- The uncertainty is the difference between the bigger result and the smaller one.
-- For the percent uncertainty, find out what percent that difference is of the (r = 1.56) volume.
(Divide the difference of the two volumes by the volume you get with r=1.56 .
Multiply the result of the division by 100, and you have the percent of uncertainty.)
(Just knocking it out quickly on our calculator, we get about 9.93% uncertainty.
This may or may not be correct, and you should not depend on it. But if you get
the same answer, then we're probably both right.)
Here's an important tool that you'll need to do this job:
Volume of a sphere = 4/3 (pi) (radius)3
380 - 35 percent percent equals 2.47
15 percent 0 equals 0; 0 percent 15 equals 0. Both the above are true
1 percent of an amount equals that amount divided by 100. So, 1 percent of 13.39 equals 0.1339. Therefore, 2 percent of 13.39 equals 0.2678.
10 percent of 100 equals 10.
187.5 percent percent = 0.01875
380 - 35 percent percent equals 2.47
Yes
"30 percent of 122 equals 85.4" is false. 30 percent of 122 equals 36.6.
62000 x 3/17 = 10941.18
71 equals what percent of 161
15 percent 0 equals 0; 0 percent 15 equals 0. Both the above are true
8.25 percent of 212.50 equals 17.53 (rounded).
No, 300 percent of 60 equals 180
10 percent of 100 equals 10.
1 percent of an amount equals that amount divided by 100. So, 1 percent of 13.39 equals 0.1339. Therefore, 2 percent of 13.39 equals 0.2678.
187.5 percent percent = 0.01875
16 percent
