Answer:
2 inches
Step-by-step explanation:
Since his actual height was 4 feet and 2 inches, instead of the estimate of 4 feet, the difference was 2 inches.
This means the error in inches was also 2 inches, since the estimated height was 2 inches lower than the one at the doctor's office.
So, the error is 2 inches
The solution would be like this for this specific problem:
Volume of a cylinder = pi * r^2 * h
Volume of a cone = 1/3 * pi * r^2 * h
Total Height = 47
Height of the cone = 12
Height of the cylinder = 35
If the top half is filled with sand, then:
volume (sand) = pi * 4^2 * 36
volume (cone) = 1/3 * pi * 4^2 * 12
Total volume = 1960.353816 cubic millimeters
353816 / (10 * pi) = 62.4 seconds.
It will take 62.4 seconds until all of the sand has dripped to the bottom of the hourglass.

I doubt your teacher would want you to evaluate the whole thing but if they do leave a comment
Answer:
trueeee :) that is my answer
Answer:
Step-by-step explanation:
Start by making the denominators of both fraction the same. This can be done by multiplying one fraction's denominator by the other.
After simplifying and combining the two fractions together, check if the numerator can be factorised such that there is a common factor in the denominator and numerator. In this case, the numerator cannot be factorised.
Lastly, expand the denominator.
