Answer:
Step-by-step explanation:
Curved surface area=
where R is radius and H is height
Since H=6R then curved surface area=
Therefore,
and making R the subject
Therefore, H=6R=6*3.000604=18.00362 m
Therefore,
Answer:
Answer on Question #47534 – Math – Geometry
How to prove the volume formula of con is 1/3×π×r^2×h;without using
integration?
Solution.
Suppose we take a slice of the pyramid with the cone inside, from some way up
the pyramid. This will look like a square with a circle fitting inside. Radius of the
cone at this point, will be x.
The area of the circle is
The area of the square is × =
The ratio of the circle to the square is
.
The same is true for every slice we take: the area of the circle is
of the area
of the square.
So, the volume of the cone will be
the volume of the pyramid.
The pyramid's volume is
.
So the cone's volume is
∗
=
Answer:
m<H=30 degrees by the Triangle Sum Theorem, so <H=<V. <G=<U, they are right angles. If GH=UV, triangle FGH=triangle TUV by the ASA.
x=3 and y=8
Step-by-step explanation:
H equals 30 by 180-150=30 (getting 150 by adding 60 and 90)
I know this is not much of a answer, but I hope it helps a little.
