Answer:
39 pi cubic inches
Step-by-step explanation:
The volume of a cone is (1/3)(area of the base)(height).

Find the area of the circular base. The circumference of a circle is
, so

Now that you know the radius of the circular base, you can find its area:

The height of the cone is 13. Time to use the volume formula.

Answer:
Step-by-step explanation:
N(106,14²)
(calculated using excel, let me know if you were supposed to use a normal table) = 0.4715
85.34
Q1:96.56
Q3:115.44
IQR (which is Q3-Q1)= 115.44-96.56= 18.88
Answer:68.2
Step-by-step explanation:
cos6=71/EF
cos6= 0.960170286650366
0.960170286650366= 71/EF
0.960170286650366*71=EF
EF= 68.2
Answer:
Step-by-step explanation:
If you have a calculator do pie times radius squared times height. So basically pie times 25 squared times 40
