Answer:
V = 500 pi in^3
or approximately 1570 in ^3
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h where r is the radius and h is the height
The diameter is 10. so the radius is d/2 = 10/2 =5
V = pi (5)^2 * 20
V = pi *25*20
V = 500 pi in^3
We can approximate pi by 3.14
V = 3.14 * 500
V = 1570 in ^3
1813 x

= 326.34
18% of 1813 people is 326.34 people
333 is a reasonable estimate.
Answer:

Step-by-step explanation:
we know that

She drove from her house to the airport and back 2 times
so
Multiply the distance from her house to the airport by 4

The constant proportionality is whats left over
