Answer 2

Answer:

Hence, the surface area of cylinder is:

345 square inches.

Step-by-step 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:

$d=2r\\\\r=\dfrac{d}{2}$

This implies that:

$r=\dfrac{10}{2}=5inches$

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:

$SA=2\times 3.14\times 5\times (6+5)\\\\SA=31.4\times (11)\\\\SA=345.4 square inches$

Hence, the surface area of cylinder is:

345 square inches.
