Find the total surface area of a cylinder with diameter of base 28 cm and height 70 cm. (Take π=\(\frac{22}{7}\))

7392 cm²

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
