Answer:
Graph B
Step-by-step explanation:
Just took test
We know that
surface area of the cone (SA)=pi*r²+pi*r*l
where
r is the radius
l is the slant height
SA=306*pi cm²
diameter=12 cm
r=12/2----> r=6 cm
SA=pi*r²+pi*r*l--------> [SA-pi*r²]=pi*r*l----> l=[SA-pi*r²]/[pi*r]
l=[306*pi-pi*6²]/[pi*6]---> [306*pi-36*pi]/[6*pi]---> 45 cm
the answer is
<span>the length of the slant height is </span>45 cm

Answer:
Step-by-step explanation:
Going from (1, -2) to (3,6), x increases by 2 and y increases by 8. Thus, the slope m of this line is m = rise / run = 8/2 = 4.
I think you meant, "What is the EQUATION of the line that passes through the point (-1, 1) and is parallel to a line that passes through
(3, 6) and (1, -2)? We have seen that this slope is -4.
Starting with the point-slope equation of a line, we have:
y - 6 = -4(x - 3)
Please, Karla, explain what "C" and "n" represent. Are you talking about combinations (for example, n+2 objects taken n at a time? Or is C some kind of function? I don't quite see the relationship of this problem to 'data management.'
