Answer:
65
Step-by-step explanation:
The slant height of a cone is the length of a segment from the base to the vertext along the surface of the cone.
You can use the given dimenstions as the legs of a right triangle, and the slant heifght is rthe hyopotenuse.
L^2 = r^2 + h^2
L^2 = 5^2 + 12^2
L^2 = 169
L = 13
The slant heiht is 13 cm.
LA = (pi)rL
LA = (pi)(5 cm)(13 cm)
LA = 65(pi) cm^2
