What is the total surface area of a cylinder having radius of base as 7 cm and height as 5 cm?
Answer & explanation
Correct answer: option 2
We know that,
Total surface area of a cylinder = 2πr(h + r)
We have,
Height =5 cm
Radius = 7 cm
= 2 × \(\frac{22}{7}\) × 7× (7 + 5) = 2 × \(\frac{22}{7}\) × 7× 12 = 528 cm2
