Find the total surface area of a cylinder with diameter of base 28 cm and height 70 cm. (Take π=\(\frac{22}{7}\))
Answer & explanation
Correct answer: option 4
We know that,
Total surface area of cylinder = 2πr(h + r)
We know the diameter of cylinder = 28cm
Radius of base of Cylinder = \(\frac{28}{2}\) = 14 cm
Height of cylinder = 70 cm
Total surface area of cylinder = 2 × \(\frac{22}{7}\) × 14 ( 14 + 70 ) = 7392 cm2
