Answer:

$V=226.08\ ft^3$

Step-by-step explanation:

we know that

The volume of a cylinder is equal to

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

where

r is the radius of the base of the cylinder

h is the height of the cylinder

we have

$r=6\ ft\\h=2\ ft\\\pi=3.14$

substitute the given values in the formula

$V=(3.14)(6)^{2}(2)\\ V=226.08\ ft^3$

Answer:

Ben's

Step-by-step explanation:

If E is the amount of energy that each full set of panels produces, then ...

3 of Ismael's 5 panels produce 3/5E

4 of Ben's 6 panels produce 4/6E

We can compare these fractions when they have a common denominator.

3/5E = 18/30E . . . . energy from Ismael's panels

4/6E = 20/30E . . . energy from Ben's panels

18/30 < 20/30 . . . . so Ben's panels are producing more energy

Answer:

$\frac{5}{6}$

Step-by-step explanation:

The total number of squares is 36, and only 6 of them are shaded therefore, the remaining 30 are not shaded. The probability that a randomly selected square is not shaded would therefore be:

$\frac{30}{36} = \frac{10}{12} \\ = \frac{5}{6}$
