The volume of a cylinder varies jointly with the square of its radius and with its height: V=kr^(2)h Cylinder A has a volume of
Brrunno [24]
We have the following equation:
 V = kr ^ (2) h
 For cylinder A we have:
 251.2 = k * ((4) ^ (2)) * (5)
 Let's clear k:
 k = 251.2 / (((4) ^ (2)) * (5))
 k = 3.14
 For cylinder B we have:
 V = 3.14 * ((3) ^ (2)) * (9)
 V = 254.34 in ^ 3
 Answer:
 the volume of cylinder B is:
 V = 254.34 in ^ 3

Daniel wanted to know his approximate score on the final exam for his mathematics class. His professor hinted that his score was
hammer [34]

Answer:   The raw score for Daniel's exam grade is 101.69.

Step-by-step explanation:

For x be any random variable.

Formula for z-score :

z=\dfrac{x-\mu}{\sigma} , where \mu = population mean

\sigma = population standard deviation.

Let x be the raw score for Daniel's exam grade.

As per given , we have

\mu=90 , \sigma=7 and z= 1.67 , put these values in the above formula , we get

1.67=\dfrac{x-90}{7}\\\\\Rightarrow\ x-90=7(1.67)=11.69\\\\\Righarrow\ x=11.69+90=101.69

Hence, the raw score for Daniel's exam grade is 101.69.

What’s the ara of each figure?
Grace [21]

Answer:

433 in.²

Step-by-step explanation:

Divide the figure into 2 rectangles

Area of the figure = area of the bigger rectangle + area of smaller rectangle

✔️Area of bigger rectangle = L*W

L = 29 in.

W = 13 in.

Area of the bigger rectangle = 29*13

= 377 in.²

✔️Area of the smaller rectangle = L*W

L = 7 in.

W = 8 in.

Area of the bigger rectangle = 7*8

= 56 in.²

✅Area of the figure = 377 + 56 = 433 in.²
