Answer 2

Hence, the surface area of cylinder is:

345 square inches.

Explanation:

We are given height(h) of the cylinder as: 6 inches.

Also, The diameter(d) of the circular base of the figure is 10 inches.

Hence, the radius(r) of the circular base is given as:

`d=2r\\\\r=(d)/(2)`

This implies that:

`r=(10)/(2)=5inches`

Now, the approximate surface area( SA) of cylinder is given as:

`SA=2\pi r(h+r)`

so, on putting value of r,h and
`\pi` in the formula we have:

`SA=2* 3.14* 5* (6+5)\\\\SA=31.4* (11)\\\\SA=345.4 square inches`

Hence, the surface area of cylinder is:

345 square inches.
