What is the total surface area of a solid right circular cylinder of radius 7 cm and height 8 cm? ($π =\frac{22}{7}$)
Answer & explanation
Correct answer: option 2
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
