Answer:
w = -10,6
Step-by-step explanation:
w(4+w)=60
4w + w^2 -60 = 0
w^2 +4w -60 = 0
w^2 +10w -6w -60 = 0
w(w+10) -6(w+10) = 0
w = -10, 6
The correct question is
<span>A cylinder has a volume of 320 pi in</span>³<span>. and a height of 5". Find the radius of the cylinder</span>
we know that
[volume of a cylinder]=pi*r²*h----> r²=volume/(pi*h)
r=√[volume/(pi*h)]
volume=320*pi in³
h=5 in
so
r=√[320*pi/(pi*5)]--------> r=8 in
the answer is
8 in
5.5 × 2= 11
11 is the length.
perimeter= 11+11+5.5+5.5
The perimeter is 33 units.
1 3/8 the denominators have to be the same so you multiply 2 to 3/4 to get 6/8 btw they are common denominators so you can easily multiply two and the you add the to get 11/8 and if you simplify it you'll get 1 3/8
