Answer:
Step-by-step explanation:
1: Base Surface Area = π×72
= 153.9380400259 millimeters2
Lateral Surface Area = π×7×√72 + 142
= 344.215921821 millimeters2
Total Surface Area = 498.1539618469 millimeters2
Rounded = 500 millimeters2
2:Base Surface Area = π×52
= 78.539816339745 centimeters2
Lateral Surface Area = π×5×√52 + 102
= 175.62036827602 centimeters2
Total Surface Area = 254.16018461576 centimeters2
Rounded 300 centimeters2
