Answer:
It's 4,570,000,000.
Step-by-step explanation:
The first guy had a typo right after the 7.
4,575,000,000
800 centimeters.......
4π(w+1)(w-1)
The total surface area of the cylinder
= 2 x area of base circle + area of vertical surface
= 2x pi x radius^2 + 2x pi x radius x height
= 2π(w-1)^2 + 2π(w-1)(w+3)
= 2π[w^2-2w+1 + w^2+2w-3]
= 2π(2w^2-2)
= 4π(w^2 - 1)
= 4π(w+1)(w-1)
A is the correct answer :)
