Answer:
360pi
Step-by-step explanation:
First find the surface area of the base:
10^2*pi=100pi for the surface area of the base
You need to find the lateral height for the rest of the surface area.
By pythagorean: 10^2+24^2=676 which is 26 squared
26*half of circumfrerence: 26*10pi=260pi
Add both parts: 260pi+100pi=360pi
