A cylinder has a volume of 175 cubic units and a height of 7 units. The diameter of the cylinder is
VashaNatasha [74]
The answer is <span>10 units
</span>
The diameter of the cylinder (d) is the twice of its radius (r): d = 2r

The volume (V) of the cylinder with radius r and height h is:
V = π r² h

We have:
d = 2r
r = ?
h = 7
π = 3.14
V = 175π

175π = π * r² * 7
175 = r² * 7
r² = 175/7
r² = 25
r = √25
r = 5


d = 2r
d = 2 * 5
d = 10

irina [24]

Answer:

$9500

Step-by-step explanation:

Given, Option A: Hourly wage is $19 and the salesperson works 40 hours per week. So, he will earn in a week= 19 X 40 = $760

Now, according to option b, he will get 8% commission on weekly sales.

Let. x = the amount of weekly sales.

To earn the same amount of option A, he will have to equal the 8% of x to $760

So, 8x/100= 760

Or, 8x= 76000

Or, x= 76000/8= 9,500

the salesman needs to make a weekly sales of $9,500 to earn the same amount with two options.
