A cylindrical container, closed at both ends, has a radius of 7 cm and a height of 5 cm. Use this information to answer the questions below. Find the total surface area of the container.
Attached Figure / Diagram
A
35 cm\(^2\)
B
528 cm\(^2\)
C
154 cm\(^2\)
D
220 cm\(^2\)
Verified Correct Answer: B.
Step-by-Step Mathematical Solution
Total surface area = 2\pir\(^2\) + 2\pirh = 2\pir(r + h) ⇒ 2 \times \(\frac{22}{7}\) \times 7 \times (7 + 5) ⇒ 44 \times 12 = 528 cm\(^2\)
