$In the diagram, the base diameter is 14cm while the height is 12cm. Calculate the total surface area if the cylinder has both a base and a top.[$\pi \frac{22}{7}$]$

In the diagram, the base diameter is 14cm while the height is 12cm. Calculate the total surface area if the cylinder has both a base and a top.[ $\pi \frac{22}{7}$ ]

836cm²

308cm²

528cm²

154cm²

View answer & explanation

Correct answer is A

Area(S) = 2 $\pi r^2 + 2 \pi rh = 2\pi r(h + r)$

D = 14cm, 2r = D

r = $\frac{D}{2}$

= 7cm

S = 2 x $\frac{22}{7} \times [7 + 12] = 44 \times 19$

= 836cm²
