Step-by-step explanation:
A = pi(r)²
<span>X/2 = 4/16
This is where you would use cross-multiplication.
Multiply the x with 16 and the 2 with 4.
16x = 8
Now divide everything by 16.
x = 0.5</span>

Answer:
7 cars
Step-by-step explanation:
The computation of the number of cars to be filled is shown below:
A car that is 90% full and the total people is 20 so 90% would be
= (.90)(20)
= 18
A car that is 65% full and the total people is 20 so 65% would be
= (.65)(20)
= 13
Now
Total number of people = (5)(18) + (3)(13).
= 129
Now the number of cars to be filled is
= 129 ÷ 20
= 6.45
= 7 cars
