We know, Volume of a Cylinder = πr²h

Here, r = 2/2 = 1 ft
h = 3 ft

Substitute their values, 
v = 3.14 * (1)² * 3
v = 9.42 ft³

In short, Your Answer would be: 9.42 Ft³

Hope this helps!

52 998 x 67 = (1,000 - 998) x 67
Tresset [83]

Given:

\to \bold{52,998 \times 67 = (1,000 - 998)  \times 67}

To find:

Proving

Solution:

\to \bold{52,998 \times 67 = (1,000 - 998)  \times 67}

Solving L.H.S part:

\to \bold{52,998 \times 67}\\\\\to \bold{3,550,866}\\\\

Solving R.H.S part:

\to \bold{(1,000 -998) \times 67}\\\\\to \bold{(2) \times 67}\\\\\to \bold{ 134 }\\\\

Therefore \bold{L.H.S \bold{\neq} R.H.S}

Howie sorkin can travel 8 miles upstream in the same time it takes him to go 12 miles downstream. His boat goes 15 mph in still
lozanna [386]

Answer: the speed of the current is 2.5 mph

Step-by-step explanation:

Let the speed of the boat be x miles per hour

Let the speed of the current be y miles per hour

Speed = distance / time

Time = distance/speed

If the boat goes 12miles downstream(in still water) at 15 mph then, the time is

12/ 15 = 0.8 hours

In still water, it means that it moved in the same direction with the current.

The total speed would be x + y. Therefore

x + y = 15 - - - - - - -1

If the boat goes 8 miles upstream in 0.8 hours, the the speed is

8/ 0.8 = 10 miles per hour

Assuming it moved in the opposite direction to the current.

The total speed would be x -y. Therefore

x - y = 10 - - - - - - -2

Adding equation 1 and equation 2, it becomes

2x = 25

x = 25/2 = 12.5

y = 15 - x

y = 15 - 12.5 = 2.5 miles per hour
