Its 9-1 so that would be 8 idk if you are right just noticed and though it would help
Answer:
1444.4 m2
Step-by-step explanation:
Surface Area = 2 * 3.14 * (R*R + R*L) = 2 * 3.14 * (10*10+10*13) = 1444.4 m2
Note .. You can Derive this
"Surface Area = 2 * 3.14 * (R*R + R*L)"
Using Calculus by differentiating its Volume
V = 3.14 * R * R * L
-25 would be the answer to this problem
