Step-by-step explanation:





Answer:
50.24ft^3
Step-by-step explanation:
Volume of a cylinder
= Pi r^2 h
Given
pi = 3.14
Radius r = 2 ft and
Height h = 4 ft
Therefore
Volume = 3.14 x 2^2 x 4
= 3.14 x 2 x 2 x 4
= 50.24ft^3
I'm assuming your teacher wants you to calculate the speed
1/2 = 0.5
3 & 1/2 = 3 + 1/2 = 3 + 0.5 = 3.5
If a plane flies 840 miles in 3.5 hours, then,
speed = distance/time
speed = (840 mi)/(3.5 hr)
speed = (840/3.5) mph
speed = 240 mph
<h3>Answer: 240 mph</h3>
