Question

Find the SURFACE AREA of the figure.*1 point4 cm8

Answer 1

STEP 1

Identify what is required and allocate data rightfully.

Height = 8cm

Radius = 4cm

The surface area of a cylinder is given as

`2\pi r^2+2\pi rh`

where r is radius and h is height.

STEP 2

We get the surface area for this particular cylinder as

`\begin{gathered} 2\pi*4^2+2\pi*4*8 \\ =32\pi+64\pi\text{ = 96}\pi=301.593cm^2 \end{gathered}`

SURFACE AREA = 301.6 sq cm
