Answer:

the answer is 15

Step-by-step explanation:

Given data:

Volume V = 45 π and radius  

r = 3 units The formula for the volume of the cylinder is  V = B · H

Base of the cylinder is:

B = r² π = 3² π = 9 πFrom the formula  V = B · H we get H:H = V / B = 45 π / 9 π = 5 units

H = 5 units

Answer:

The height is 5

Step-by-step explanation:

Given data:

Volume V = 45 π and radius  r = 3 units

The formula for the volume of the cylinder is  V = B · H

Base of the cylinder is:

B = r² π = 3² π = 9 π

From the formula  V = B · H we get H:

H = V / B = 45 π / 9 π = 5 units

H = 5 units

Three potential employees took an aptitude test. Each person took a different version of the test. The scores are reported below
Anastaziya [24]

Answer:

Nico

Step-by-step explanation:

In order to compare who had the best performance on the aptitude test, we can use Z score. Z score indicates how many standard deviation a result  is over the mean. For this case the higher the result is, the best is the performance on the aptitude test.

Z score is expressed with the following formula:

Z=(X-μ)/σ

Where:

X is the test score

µ is the mean

σ is the standard deviation

Replacing in the formula we obtained

For Nico:

X = 88.3

µ = 66.2

σ = 13

Z=(88.3-66.2)/13=1.7

For Justin:

X = 226.2

µ = 216

σ = 17

Z=(226.2-216)/17=0.6

For Tera:

X = 7.97

µ = 7.2

σ = 0.7

Z=(7.97-7.2)/0.7=1.1

Nico had the higher Z score which means he had the better performance on the test and he should be offered the job.

The dog spa in Champlin has an outside play area. Each play area is in
RoseWind [281]

Answer: $12,723.45

Step-by-step explanation:

Details of each play area :

The radius of circle = 18 feet long

Cost of fake grass per square foot = $12.50

Therefore,

We can obtain the Area of the play area by calculating the area of the circle:

Area of a circle = πr^2

Area = π × 18^2

Area = 1,017.876ft^2

Since the cost per square foot is $12.50

Therefore, Cost of 1,017.876 ft^2 equals

Cost per square foot × Area of play area

($12.50 × 1,017.876)

= $12,723.45
