Answer:
= r
Step-by-step explanation:
V = 1/3 pi r^(2) *h
Rewrite:
V = pi * r^(2) * h/3
Inverse operations:
V / h / 3 = pi * r^2
Simplify:
3V/h = pi * r^2
Inverse operations:
3V/h / pi = r^2
Simplify:
3Vpi/ h = r^2
Inverse operations:
sqrt( 3Vpi/h) = r
= r

Let the number of buses be x
and car be y
• Total vehicle gone are 21
x + y = 21 ..... ( i ) × 4
• There are 30 people in buses and 4 on car total people gone are 318
30x + 4y = 318 ..... ( ii )
Sub ( ii ) from ( i ) × 4
4x + 4y - ( 30x + 4y ) = 84 - 318
4x + 4y - 30x - 4y = - 234
- 26y = - 234
y = 9
Putting the value of y in eq i
x + y = 21
x = 21 - 9
x = 12
Total buses are 12
and total car are 9
