Question

Which equation can be used to find the surface area of the cylinder? d=6cm h=14cm

S=2pie(14)^2+2pie(14)(6)
S=2(3)^2+2(3)(14)
S=2pie(6)^2+2pie(6)(14)
S=2pie(3)^2+2pie(3)(14)

Answer 1

d

Explanation:

Answer 2

`SA=(2)\pi (3)^(2)+ 2\pi (3)(14)`

Explanation:

we know that

The surface area of a cylinder is equal to

`SA=2\pi r^(2)+ 2\pi rh`

we have

`r=6/2=3\ cm` ----> the radius is half the diameter

`h=14\ cm`

substitute the values

`SA=(2)\pi (3)^(2)+ 2\pi (3)(14)`
