Mike has a barrel in the barn to keep water for his cows. The barrel is 4.5 feet tall and has a diameter of 3 feet. Approximatel

sergiy2304 [10]

Answer:

Approximately $238\ gallons$

Step-by-step explanation:

we know that

The volume of a cylinder (barrel) is equal to

$V=\pi r^{2}h$

in this problem we have

$h=4.5\ ft$

$r=3/2=1.5\ ft$ -----> the radius is half the diameter

substitute

$V=(3.14)(1.5^{2})(4.5)=31.7925\ ft^{3}$

<u>Convert to gallons</u>

$31.7925\ ft^{3}*7.5=238.44\ gallons$

Rob can lift less than 135 pounds at the weight room. There is already 48 pounds of weights on the bar. Write an inequality that

Rama09 [41]

Answer:

$x + 46 < 135$

Step-by-step explanation:

Given

$Initial\ Weight = 48lb$

He can lift less than 135 implies that, his maximum is:

$Total < 135$

Required

Determine the additional weight

Let the additional weight be x

Such that

$Total = x + Initial\ Weight$

$Total = x + 46$

Substitute x + 46 for Total in $Total < 135$

$x + 46 < 135$

<em>Hence, the inequality that describes the scenario is: </em> $x + 46 < 135$ <em></em>
