Please help me please I reallly need help
kiruha [24]

Answer:

we have:

v  =  \frac{1}{3} \pi \: r {}^{2}h \\  \\  =  > 60\pi =  \frac{1}{3} \pi \: r {}^{2} h \\  \\  <  =  > 180 = r {}^{2} h

=> r²h = 10.18 = 9.20 = 5.36 = 6.30 = 4.45 = 12.15

=> only r²h = 5.36 satisfy the problem

=> h = 5

h = 5 r = 6

h = 5 r = 6=> d = 12

Using this diagram, select the pair of lines that must be parallel.
Bas_tet [7]

Answer:

The answer would be D: d || f.

Step-by-step explanation:

  1. Since the angles 4 and 7 are parallel, it would make sense for the lines that the angles are on to be parallel as well.
  2. It just so happens that line d and line f are completely parallel to each other and angles 4 and 7 are on the lines. So the answer would be D.

Butoxors [25]

42.86% error was in the scientist's estimation.

Step-by-step explanation:

Given data;

Approx amount = 4 ml

Exact amount needed = 7 ml

Percentage error = \frac{|Approx-Exact|}{Exact}*100

Percentage\ error=\frac{|4-7|}{7}*100\\Percentage\ error=\frac{|-3|}{7}*100\\Percentage\ error=\frac{3}{7}*100\\\\Percentage\ error=\frac{300}{7}\\Percentage\ error= 42.86\%

42.86% error was in the scientist's estimation.
