Find the total surface area of a container in cylindrical shape whose diameter is 14 cm and height is 25 cm. [Use π = 22/7]
Answer & explanation
Correct answer: option 3
We know that,
Total surface area of the cylinder = 2πr(h+r)
Diameter = 14 cm
height = 25 cm.
Radius of the cylinder = \(\frac{14}{2}\) = 7
Total surface area of the cylinder = 2 × \(\frac{22}{7}\) × 7(25 + 7) = 1408 cm2
