1188 = π<em>r</em>²<em>h</em>
For the formula to solve for <em>h, </em>you have to change the equation to:
<em>h </em>= 1188/π<em>r</em>²
which is just moving h to the left side of the equation, and moving v(in this case 1188) to the right side.
because <em>h </em>was multiplied to the original equation, switching sides in an equation makes its replacement(1188) into a devision. (if you move a number across the = sign, the number will become the opposite of itself.)
Since you don't know the radius, you can't simplify this equation.
The answer is <em>h </em>= 1188/π<em>r</em>²
Answer is last one. last one is false
Every real number is a rational number
example:
square root (3) is real number
but square root (3) is not a rational number
hope it helps
Tanα=h/x
x=h/tanα
x=70/tan38 ft
x≈89.6 ft (to nearest tenth of a foot)
Note: the question seems strange, (because this would make the ladder almost 114 feet long!) or are we to assume as I did that the ladder is leaning against a point 70 feet high, or should if be a 70 foot ladder leaning against a wall of unknown height?
If it is just a 70 ft ladder at a 38° inclination the:
cosα=x/L
x=Lcosα
x=70cos38° ft
x≈55.2 ft
