Which graph shows the image being rotated 90°?

3rd image

Step-by-step explanation:

You can see that.

The surface area of the smaller ganza is 94.5π, the surface area of the larger ganza is 330π, and the weight of the larger ganza is 3.8 lbs.

The surface area of a cylinder is found by using the formula
SA=2πr²+πdh.  This is based on the formula for the area of a circle, with there being two circles on the cylinder; and the circumference of a circle, which is the length of the rectangle "wrapped around" the cylinder, multiplied by the length of the cylinder.

Substituting our known information for the small ganza we have:
SA=2π(3.5²)+π(7)(10) [if the radius is 3.5, the diameter is 2*3.5=7]

Simplifying, we have:
SA=24.5π+70π=94.5π

Substituting the known information for the large ganza we have:
SA=2π(5.5²)+π(11)(24.5)

Simplifying, we have:
SA=60.5π+269.5π=330π

We set up a proportion to find the weight of the large ganza:

94.5π/1.1 = 330π/x

Cross multiplying we have:
94.5π*x = 330π*1.1
94.5πx=363π

Divide both sides by 94.5π:
94.5πx/94.5π = 363π/94.5π
x ≈ 3.8
