First you add 3 twice to both sides of the swimming pool
12 + 6 = 18
15 + 6 = 21

The perimeter is the sum of all sides therefore 

18 + 18 + 21 + 21 = 78



The answer is A

Answer:

\frac{1}{4k^3}

Step-by-step explanation:

It's already in a form that only ha positive exponents.  Just to state it though you could rewrite it as k*(4k^{4})^{-1} or k*4^{-1}*k^{-4}  The question asks for positive exponents though so yu don't need to do that.

You also need to know \frac{x^a}{x^b}=x^{a-b} so in this case \frac{k}{k^4}=\frac{k^1}{k^4} =k^{1-4}=k^{-3}=\frac{1}{k^3}

so \frac{k}{4k^4}=\frac{1}{4}*\frac{k}{k^4}=\frac{1}{4}*\frac{1}{k^3}=\frac{1}{4k^3}

yes, she took the $100 bill and gave it, got back $30, that means she only kept $30 from the original bill.

the store however, lost the original $100 bill plus the $70 in merchandise, so they have -$170.

A cylinder has a surface area of 1850 square meters and a radius of 9 meters. Estimate the volume of the cylinder to the nearest
iren2701 [21]
Surface area of the cylinder = 1850 square meters
Radius = 9 meters
Surface area of cylinder = 2*pi*r*h
1850=2*22/7*9*h
h      = 1850*7/2*22*9
        = 32.7 meters

Volume of cylinder = pi*r*r*h
                              = 22/7*9*9*32.7
                              = 8324.48  = 8324 (approx) cubic meters

Can someone explain, please?
qaws [65]
I see that 3 would be the diameter
But to find area we would need to have the
R*R*3.14
So 3/2 would be 1.5
Now we plug it in
1.5*1.5*3.14= 7.065
A= 7.06
