18pi
Step-by-step explanation:
Ⓗⓘ ⓣⓗⓔⓡⓔ
Well, if the diameter is 18, the radius is 9.
If he needs edging, he's building a fence-like-structure around the garden which will be the circumference.
The formula for circumference is 2*pi*r
We'd just plug in 9 for r.
2*pi*9=18pi

<span>The only type of transformation that can make a graph more narrow/wide is a scaling transformation. A scaling transformation involves a multiple factor. The answer to your question is B. </span>I hope that this is the answer that you were looking for and it has helped you.
136 would be your answer
you start by finding the area of the square , which would be 128, then you divide 16 by four which would be 4 , and then four times two is eight , 128+8 is 136
D=dimes
q=quarters
d + q = 20
.10d + .25q = 3.05
d=-q + 20
.10(-q + 20) +.25q = 3.05
-.10q + 2 + .25 = 3.05
.15q + 2 = 3.05
.15q + 2 - 2 = 3.05 - 2
.15q = 1.05
.15q/.15 = 1.05/.15
q = 7
d + 7 = 20
d + 7 - 7 = 20 - 7
d = 13
Sally has 7 quarters and 13 dimes.
Hope this helps!
