Answer:
pls mark me brainlist .......my question was the same but no one ans I don't know
Answer:
Step-by-step explanation:
the information we have is:
- the radius of the circle in the base: (u for units)
- and the height of the cone:
to find the volume we need the formula for the volume of a cone:
where r is the radius and h is the height.
Substituting the known values to find the volume:
the volume in terms of is
and if we substitute the value of pi: we get:
In similar figures, the angle measures are the same but the side lengths are different. So in #4, x = 42. Since all the angles of a quadrilateral added up equal 360, then y is 360-90-90-42=138. For number 5, make sure you match up the sides correctly in your ratio:
. You could cross multiply to get 4x=16, and x = 4, or you could just realize that reducing 4/8 will give you 2/4 and x = 4. Going back to the idea that in similar shapes corresponding angles are the same measure, x in #6 is 63
A + k = 600
k = 2/3a
a + 2/3a = 600
3/3a + 2/3a = 600
5/3a = 600
a = 600 * 3/5
a = 1800/5
a = 360
k = 2/3a
k = 2/3(360)
k = 720/3
k = 240
so Kim's pay is $ 240 and Alicia's pay is $ 360
