B One of these numbers is the area of the outside curved surface of the cylinder, in cm', using = 3. Which one?
A 15 B 30 C 1000 D 1500 E 3000

B

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.
