33/100 as a decimal is 0.33
Answer:
14
Step-by-step explanation:
Range = Maximum value - minimum value
= 6 - (-8)
= 6 + 8
= 14
If the amount of weeks is w, then -1.5w is the amount of hair cut off due to that she subtracts 1.5 from her hair every week. Therefore, since the base amount is 11.5, we have to add that to the expression to get 11-1.5w
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
