Vol. of a sphere is V = (4/3)*pi*r^3, so in this case,
4*pi*19683
V = (4/3)*pi*(27 inches)^3 = ------------------ cubic inches
3
... which can be reduced to 26244 pi cubic inches, or 15.2 cubic feet
Answer:
<1=83
<2=97
<3= 83 (given)
<4=97
<5=83
<6=97
<7=83
<8=97
Step-by-step explanation:
They give you the angle for 3 which is 83, so from there all you have to do is find the equivalent angles which are angle 1,5,7. Then for angles 2,4,6,8 you subtract 83 from 180 and you get 97.
Each child = 2 + 5
Three children = (2 + 5) x 3
Ansswe is B. 3 x (2 + 5)

Answer:
x=45
Step-by-step explanation:
both angles are opposite angles with the same measurements
Set your formula up as
x+30=2x-15
30=2x-15-x
45=x
Now substitute 45 in place of x
x+30
45+30 = 75
2x-15
2*45-15 = 75
