Help me please, someone

Step-by-step explanation:

Hey there!

Well the formula to find the surface area of a cylinder is,

,

So with the h and r being 10 and 4 lets plug it in.

Let's solve!

2π40 + 2π16

80π + 32π

251.3 + 100.5

=

Hope this helps :)

351.9 mi^2

Step-by-step explanation:

The surface area of a cylinder can be found using the following formula.

We know that the height of the cylinder is 10 miles and the radius is 4 miles.

h= 10 mi

r= 4 mi

First, evaluate the exponent 4 mi^2.

4 mi^2= 4 mi * 4 mi = 16 mi^2

Next, multiply 16 and 2pi

Next, multiply 4 and 10

Multiply 40 and 2 pi

Add the 2 numbers together

Round to the nearest tenth. The 5 in the hundredth place tells us to round the 8 to a 9 in the tenth place.

The surface area of the cylinder is about 351.9 square miles.
