It should be B . 215
Sindrei [870]3 years ago

I believe it is B. This is easy to figure out: divide 8.6 by 2 (4.3) then multiply it by 50 (215). At least, that's what I believe. Hope I could help!

The top of a tower is a cone with a radius of 12 feet. The volume of the cone is 1,506.96 cubic feet. Which of these is the heig
shepuryov [24]

<span>the question does not have the options, but this does not limit its resolution
</span>
we know that
volume of the cone=(1/3)*pi*r²*h
where 
r is the radius of the cone
h is the height of the cone
r=12 ft
Volume=1506.96 ft³
h=?

clear the variable h
v=(1/3)*pi*r²*h-----> multiply by 3
3*v=pi*r²*h----> divided by (pi*r²)
h=3*v/(pi*r²)------> h=3*1506.96/(pi*12²)----> h=9.99 ft---> h=10 ft

the answer is
h=10 ft

Find the area of the figure.
OLga [1]

Answer:

63in

Step-by-step explanation:

You add 5in plus 4in since they are both on the same side which would equal 9, then you go to the bottom and add 5in plus 2in which equals 7in, then you use the formula for area which is length times width and you get 63in.

Which of the following points represents the center of a circle whose equation is (x - 3)to the power of 2 + (y - 2)to the power
egoroff_w [7]
I think this is geometry. So you would have to use the standard equation of a circle. 
The standard equation of a circle with center (h,k) and a radius of r is: (x-h)^2 + (y-k)^2 = r^2
With that equation, we know that the center of YOUR equation is (3 , 2). 
So now make (x-3) and (y-2) equal to 0. 
That would make x=3 and y=2. 
Therefore the answer is A.
