The value of the rational expression is -7!!
Answer:
h≈25.47
Step-by-step explanation:
h=V/πr2
you just plug in the radius and volume into the equation
Answer: −17
Step-by-step explanation: ez
Given:
The coordinates of point A are (7,4).
It is dilated from the origin by a scale factor r = 3.
To find:
The coordinates of A'.
Solution:
If a figure is dilated from the origin by a scale factor k, then

Here, the figure is dilated from the origin by a scale factor 3, so the rule of dilation is given by:

Using this rule, we get


Therefore, the coordinates of point A' are (21,12).
