For a quadratic of the form
, we can solve by completing the square.
First, we must expand the expression and convert it to the form above.
Completing the square is like forcing a quadratic to be factored like a perfect square trinomial. To do so, we add the square of half of the coefficient b,
, to both sides of the equation.
We then factor like a perfect square trinomial and simplify.
I am assuming the both cylinders have the same measure of radius. They only differ in height.
Larger Cylinder = 343 ft³
Smaller Cylinder = 125 ft³ ; height = 5 ft.
We can use proportion for this problem; a:b = c:d where ad = bc
5 ft :125 ft³ = x : 343ft³
5 ft * 343 ft³ = 125 ft³ * x
1715 ft⁴ = 125 ft³ * x
1715 ft⁴ ÷ 125 ft³ = x
13.72 ft = x height of the larger cylinder.
Cone S = 768pi cm³
Cone T = 6144pi cm³ ; height = 24 cm
24 cm : 6144 cm³ = x : 768 cm³
24 cm * 768 cm³ = 6144 cm³ * x
18,432 cm⁴ = 6144 cm³ * x
18,432 cm⁴ ÷ 6,144 cm³ = x
3 cm = x height of Cone S.
You're given the volume and height of rectangular prism.
To find the possible length and width: √144/6=24;
24 is the product of length and width, so now just divide 24 by 4 or 6 or 2 or...
24/4=6.
The possible length and width is 4 and 6.
Check: 4×6×6=144ft³
