Answer:
1. To find the volume of a cylinder you'll need to use the formula V = pi(r)^2(h)
V = pi(4)^2(6)
V = 301.59
Rounded* = 301.6
2. A beach ball is a sphere, so we're going to use the formula 4/3pi(r)^3
4/3pi(18)^3
D = 24429.02
Rounded* = 24429.0
I cant read the last one completely, hope this helps.
The volume is around 50.27
the surface area is: 75.4
the perimeter 25.13
If you would like to know how long will it take to drain the pool, you can calculate this using the following steps:
3 hours ... 250 gallons
x hours = ? ... 150 gallons (= 400 - 250)
3 * 150 = 250 * x
x = 3 * 150 / 250
x = 1.8 hours
3 hours + 1.8 hours = 4.8 hours
The correct result would be B. 4.8 hours.
