Answer:

4π(w+1)(w-1)

Step-by-step explanation:

The total surface area of the cylinder

= 2 x area of base circle + area of vertical surface

= 2x pi x radius^2 + 2x pi x radius x height

= 2π(w-1)^2 + 2π(w-1)(w+3)

= 2π[w^2-2w+1 + w^2+2w-3]

= 2π(2w^2-2)

= 4π(w^2 - 1)

= 4π(w+1)(w-1)

A fireman is heading towards a forest fire and needs to know how far away the fire is. The person in the fire tower can determin
hjlf

Answer: 3.82 miles

Step-by-step explanation:

According to the shown figure, we can imagine the scene as a <u>right triangle</u>, where the tower is located at the right angle, and the fireman and the forest fire located at each of the other two vertices.

So, since we are dealing with a right triangle we can use the Pithagorean Theorem, in order to find the distance from the fireman to the fire d, which is also the hypotenuse.

d^{2}= (2.1 miles)^{2} +(3.2 miles)^{2}

d=\sqrt{(2.1 miles)^{2} +(3.2 miles)^{2}}

Finally:

d=3.82 miles
