Answer:
1.9099
Step-by-step explanation:
V = (PI) * r^2 * (h/3)
32 = (PI) * (16) * (h/3)
6/PI = h
1.9099 = h
Answer:
the answer is 37.68
Step-by-step explanation:
C=2 x pi x r
C = 2 x 3.14 x 6 the radius is 6 because you divide the diameter by 2 to get the radius which is 6 in thsi case.
2x3.14x6=37.68
The percentage of change: This is how you set it up
% change = (New old value) =
(Old value) = x 100 %
40 is the old value and 72 is is the new value
The new value is greater than the old value.
(72 - 40) /40)x 100 = 80 or 80%
the percent change from 40 to 72 represents a positive change (increases) of 80.
Let children be x
Adult be y
5.10x+9.40y=1184.20 ... 1
x+y=158 ... 2
From 1// 510x+940y=118420 ... 3
From 2// y=158-x ... 4
Sub 4 into 3
510x+940(158-x)= 118420
510x+148520-940x=118420
-430x= -30100
x=70
As we know that children are x, 70 children tickets were sold.
2(x-2)=9
Hope this helps !! have a good day
