The radius of a cylindrical gift box is (2x+3) inches. The height of the gift box is three times the radius. What is the surfa

Natalija [7]

Answer:

$S(x)=32\pi x^2+96\pi x+72\pi$

Step-by-step explanation:

The surface area of a cylinder is given as $S.A=2\pi r(r+h)$

We have that the radius of the box is $r=2x+3$ inches.

The height of the gift box is three times the radius.

$\implies h=3(2x+3)\\\implies h=6x+9$

We substitute into the formula to get:

$S.A=2\pi (2x+3)(2x+3+6x+9)$

We simplify the last parenthesis to get:

$S.A=2\pi (2x+3)(8x+12)$

We expand the last two binomial factors to get:

$S.A=2\pi(16x^2+48x+36)$

We expand further to get:

$S.A=32\pi x^2+96\pi x+72\pi$

Can somebody please explain how to do this?

erastova [34]

As we already have the value of y,we can put it into another equation.

Here's how we can solve the equation:

y = 2x+48...(1)
y = 8x...(2)

Put (2) into (1)

(8x) = 2x+48
8x-2x = 48
6x = 48
x = 8...(3)

Put (3) into (1)
y = 8(8)
y = 64

Thus, x=8, y+64

Hope it helps!
