We will determine the radius using the volume
formula.
==> V = r^2 * pi *
h
==> 588pi = r^2 * pi *
12
We will reduce
pi.
==> 588 = r^2 *
12
Now we will divide by
12.
==> r^2 = 588/12 =
49
==> r = 7
Now let us
calculate the surface area.
==> surface area =
2*area of the base + area of the sides.
==> area of
the base = r^2 * pi= 7^2*pi = 49pi
area of the side =
circumference * h = 2*pi*r *h = 2*7*pi*12 =
168pi.
==> surface area = 2* 49pi + 168pi= 98pi +
168pi = 266pi = 835.66
Then the
surface area of the cylinder is SA = 266pi = 835.66 square
units.
