Okay, here we have this:
Considering the provided figure and measures, we are going to calculate the requested surface area, so we obtain the following:
So to calculate the surface area we will substitute in the following formula:
A = 2πr(h+r)
Replacing:
A = 2πr(h+r)
A = 2π(8 cm)(4 cm+8 cm)
A = 2π(8 cm)(12 cm)
A = 2π(96 cm^2)
A = 192π cm^2
A= 603.2 cm^2
Finally we obtain that the total surface area is 603.2 cm^2.
