What is the total surface area of a solid right circular cylinder of radius 7 cm and height 8 cm? ($π =\frac{22}{7}$)

660 cm²

We know that,

The surface area of the right circular cylinder = 2πr(r+h)

We have,

The radius of the cylinder = 7 cm

The height of the cylinder = 8 cm

The surface area of the cylinder = 2πr(r+h) = 2 × \(\frac{22}{7}\)  × 7(7+8) = 44 x 15 = 660 cm²
