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

Surface area of a sphere=4pi(r^2)
Volume of a sphere=(4/3)pi(r^3)
You need to find the r value to calculate surface area, so I'll solve for that first.
(4/3)pi(r^3)=2254pi
(4/3)(r^3)=2254
r^3=1690.5
r=(1690.5)^(1/3), around 11.9126m
Substitute this in to find surface area
A=4pi(r^2)=4pi(11.9126)^2
=1783.2818 m^2
