$6.90 divided by 3 is $2.30 which is the unit rate and if you multiply $2.30 by 10 you get $23
Divide the part from whole
717/5000 = 0.1434
To find the percentage, move the decimal point to the right two place values
0.1434 = 14.34%
14.34% is your answer
hope this helps
The formula for percentage error is:
Ross got the approximate area as 12, while the actual area was 11.8. So, let's plug it in to the formula.
Multiply 0.0169 by 100 to make it into a percent.
0.0169 * 100 =
1.69%Ross's percentage error is
1.69%.

Answer:
B 137.32 cm³
Step-by-step explanation:
The original volume is
V = pi r^2 h
V = pi (3)^2 ( 12)
V =108 pi cm^2 = 339.12
the diameter increases by 1.12 6*1.12 = 6.72
r = 6.72 /2 =3.36
The height will increase by 1.12 so 12*1.12
V = pi ( 3.36)^2 ( 13.44)=476.4391834
The difference is
476.4391834 - 339.12 = 137.3191834
To the nearest hundredth
137.32
