1/2.54 = 90/x
Cross multiply
(1)x = (2.54)(90)
x would equal 228.6
The answer would be 90 in/ 228.6 cm.
The volume of a cone is

where r = radius and h = height. If the cone has a volume of 94.2 cm³ (I assume you didn't mean m³ because that would be ridiculously huge) and a height of 10 cm, we can plug these values into the formula to find the radius. Don't do any rounding.

Now we know that's going to be the radius of our <em>new </em>cone as well since we're keeping the diameter the same. The volume is going to be double 94.2 which is 188.4. Let's solve for the height.
21:3
9:3
3:1
there all a 3:1 ratio
If Jose bought three Chocolate Bars for 18$ 18 divided by 3 would equal 6. Therefore each Chocolate Bar would cost 6$.
Perimeter = 12
2(w+l) = 12
w + l = 6
area = 8
w x l = 8
the possibility
length = 4
width = 2
i know you can draw it
