It would be.703 i think hope this helps
Surface Area of a Cone = (pi)*(radius)*(radius) + (pi)*(radius)*(length)
radius = 5
length = 10
SA = 25pi + 50pi = 75pi or about 235.619
The answer would be $15
All you need to do is multiply each one by .4 and see which one equals 6.
15 x .4 =6
Hope this helps!
1. Subtract 8 from both sides
2. Simplify to get x= -23
The anwser is 9
my handwriting is good but if you have any more questions plz lmk
