Question

Find the surface area of the cylinder.16 cm7 cmSurface Area =7 cm2

Answer 1

136.5picm^2

Step-by-step explanation:

The surface area of the cylinder is expressed as;

`^{}\text{TSA =2}\pi r(r+h)`

r is the radius

h is the height

Given that;

height h = 16cm

diameter = 7cm

radius = 7/2 = 3.5cm

Substitute the given values into the formula;

`\begin{gathered} \text{TSA =2}\pi\text{(3.5)(3.5+16)} \\ \text{TSA}=7\pi(19.5) \\ \text{TSA}=136.5\pi cm^2 \end{gathered}`

Hence the total surface area of the cylinder is 136.5picm^2
