Answer:
ST = 12 units
Step-by-step explanation:
As RA is parallel to ET, the angle in R is equal to the angle in T, and the angle in A is equal to the angle in E, so the triangle RAS is similar to the triangle SET.
If RT is 21 units, we have that RS + ST = 21 -> RS = 21 - ST
Using a rule of three with the sides of the triangle (as they are proportional), we have:
RS / ST = AR / ET
(21 - ST) / ST = 6 / 8
4 * (21 - ST) = 3*ST
84 - 4*ST = 3*ST
7*ST = 84
ST = 12 units
In triangle TUV it shows all three medians, segments from a vertex of an angle to the midpoint of its opposite side, intersecting. If constructed correctly, all three medians will intersect in one point, point W. This intersection point can be referred to as the centroid.
For future references:
The circumcenter is the point where all three perpendicular bisectors meet
The orthocenter is the point where all three altitudes meet
The incenter is the point where all three angle bisectors meet

Answer:
-8*6=-42
Step-by-step explanation:
-42 is the answer for the question
Considering the volume of the cylinder, it is found that the height must be decreased by 18.51%.
<h3>What is the volume of a cylinder?</h3>
The volume of a cylinder of diameter d is given by:
In this problem, the diameter will be increased by 25%, hence d = 1.25d, and the volume will be of:
V = 0.390625 πd²h
Solving for the height, we have that:
h = V/0.390625 πd²
h = 0.8149 of the original, hence the height must be decreased by 18.51%.
