The height of a cylinder is 10 and the area of a base is 36 pi square units. What
ollegr [7]

Answer:

1130.97336 units^3

Step-by-step explanation:

The volume of a cylinder can be found using:

v=\pi r^2h

We have the area of the base, but not the radius

a=\pi r^2

We know the area is 36\pi, so we can substitute that in for a

36\pi =\pi r^2

We want to find r, so we need to isolate it

Divide both sides by pi

36=r^2

Take the square root of both sides

6=r

Now we know the radius, and can substitute it into the volume formula, and we can substitute the height (10) in

v=\pi r^2h

v=\pi 6^210

Solve the exponent

v=\pi 36(10)

v=\pi 360

v=1130.97336

The volume is 1130.97336 units^3

HELP PLEASE!!!
nikdorinn [45]

Answer:

Option A

Step-by-step explanation:

R = (\frac{V_f-Vi}{V_i} )100

where,

V_f is the final value

V_i if the initial value

R is the investors rate of return

so,

R = (\frac{V_f-Vi}{V_i} )100\\\\R=(\frac{1500-1700}{1700})100 \\\\R=(\frac{-200}{1700})100 \\\\R=-11.8\\

so the investors rate of return is -11.8%

Suppose f is a linear function such that f(3 = 5 and f(7 = -4. find the equation for f
NeX [460]
   
\displaystyle\\   &#10;f(3) = 5 \\ &#10;f(7) = -4\\\\&#10;\texttt{Solve:}\\\\&#10;f(x)=ax+b ~~~\Longleftrightarrow~~~ y=ax+b~~~\Longleftrightarrow~~~ ax+b-y=0\\\\&#10;-------\\&#10;3a+b-5=0~~~(E1)\\ &#10;7a+b+4=0~~~(E2)\\&#10;---\\&#10;E2 - E1\\&#10;4a+9=0\\&#10;4a =-9\\\\&#10;\boxed{a =  -\frac{9}{4} = -2,25}\\\\&#10;3\times  \Big(-\frac{9}{4}\Big)  + b -5 = 0\\\\&#10;-\frac{27}{4} -5+ b = 0\\\\&#10;\frac{-27-20}{4}  + b = 0\\\\&#10;-\frac{47}{4}  + b = 0\\\\&#10;\boxed{b = \frac{47}{4} = 11,75}

Write and solve a proportion to find the height of the building.
slavikrds [6]

Write and solve an equation of ratios:


9 ft          22 ft

------- = -----------

h               99 ft


This is appropriate because h is greater than 9 ft.


cross-multiplying, we get 

9(99) ft^2 = 22*h*ft


Then h =40.5 ft (which is the height of the building)
