Its Between C and A For me but I will see what I get! but maybe this would help explain!
y = 2x + 4 is the equation and they want to know what the orderd pair of the point that crosses the y axis is. We don't know what the orderd pair means.
-------------------------
The y-axis contains all the points where x=0.
-----------------------
If y = 2x+4, let x=0 so you can solve for "y":
y = 2*0+4
<span>
y = 4</span>
2x=3 or x=3/2 i think thats right
Step-by-step explanation:
I guess the 3.14 is to be used for pi (and not r, which is what we need to find out).
the volume of a cylinder is ground area × height.
the ground area is the area of a circle, which is pi×r².
so, we have
pi×r²×height = 115 cm³
3.14×r²×7.7 = 115 cm³
3.14×r² = 14.93506494...
r² = 4.756390107...
r = 2.18091497... cm
