Answer:
450.4
Step-by-step explanation:
To find volume of a cylinder, you must find the area of the base and multiply it by the height of the object.
V=Bh where B=area of the base. Since the base is a circle, we must find area of the circle. A=pi(r^2)
A=3.14(6^2) Since it gave us the diameter, we take half for radius. Solve A=3.14(36)
A= 113.04 square cm
Now to find volume.
V=113.04•11
V=1243.44 cubic cm
Now find volume of the cone on top.
V=1/3Bh again with B= area of the base (pi)(r^2)
Since the two objects share a base, we can use the area of the cylinder as above.
V=1/3(113.04)9
We have to do a little simple math to determine the height of just the cone. Total height is 20-11 height of the cylinder. The difference is 9.
V=1/3(113.04)9 multiply
V=339.12 cubic cm
Now add the two volumes together to find total volume.
Total V=1243.44+339.12
V=1582.56 cubic cm
Answer:
IV: colour of the room
DV: The number of minutes each group spends studying
Step-by-step explanation:
IV(Independent Variable) : is what is changed in the experiment and the colour of the room is being changed.
DV(Dependent Variable) : is what is measured in the experiment and the number of minutes in spent on studying is measured.
The slope intercept form is
y = Mx + b
x and y are the coordinates, and m is the slope. If you don’t have b, you can plug in the other numbers you do have.
EXAMPLE:
A line has a slope of -3 and a coordinate of (1, 6). What is the y-intercept (b)?
y = Mx + b
6 = -3(1) + b
6 = -3 + b
9 = b
