Line graphs can be used to compare changes over the same period of time for more than one group. Pie charts are best to use when you are trying to compare parts of a whole. They do not show changes over time.
Answer:
the volume is about 1884
Step-by-step explanation:
v of cone= 1/3(pi)r^2h
diameter to radius is 30=5.477225575051661
so 1/3(3.14)5.477225575051661^2(60)
=1/3(3.14)30(60)
=1/3(5652)
=1884
hope this helps

Step-by-step explanation:
The formula for the area of a circle is 
If this quarter circle were to be a full circle, the area would be 
Since this is a quarter circle as the angle is 90 degrees (which is a quarter of 360), the area of this shape is .
Answer:
18 cubes
1/9
2/3
Step-by-step explanation:
Disclaimer: Im in 4th grade and i know this so my advice is get bett-
a) Count the cubes, so 18
b) Volume is s^3 so (1/3)^3 is 1/9 for one cube
c) Volume for large solid is h*w*l so ({1/3)*3} times ({1/3)*3} times (1/3*2)
you get 1*1*2/3
so 2/3
The approximate length of the hypotenuse is 7.1
