Answer:
and 
Step-by-step explanation:
Given:
The rational equation to solve is given as:
We use the cross multiplication rule and multiply the numerators one side with the denominators of the other side. Therefore,
Now, for 
, the rational equation is equal to 0. So, is a solution.
Also, 
is also a solution as the equation's denominator is defined at that point.
So, no extraneous solution.
If you rotate about the leg of length 4 then the radius of the base of the cone is 6 and the height is 4.
Volume of a cone is V=1/3*pi*r^2*h
V=1/3*pi*6^2*4
=1/3*pi*36*4
=pi*48
=150.8 cm^3
To make sure that is the greatest volume we can figure the other cone.
If you rotate around the leg of length 6 your radius will be 4 and your height will be 6.
V=1/3*pi*4^2*6
V=100.5 cm^3
Answer:
well first you need to know the formula of the object then you need to multiply and divide as so
Step-by-step explanation:
you would do 3.14 times the radius times the formula and you would get you answer you radius is half of the formula
9514 1404 393
Answer:
(a) SSS
Step-by-step explanation:
Two of the sides are marked congruent, and the third side is shared (so is congruent to itself). The triangles are congruent by the Side-Side-Side (SSS) postulate.
