Answer:

  228 cm²

Step-by-step explanation:

The volume of a cylinder of radius r and height h is given by ...

  V = πr²·h

Filling in the given information, we can solve for r:

  235.5 = π·r²·12

  √(235.5/(12π)) = r ≈ 2.49937 . . . . cm

The area of a cylinder is given by ...

  A = 2πr² + 2πrh = 2πr(r +h)

Filling in the radius and height, we can find the area to be ...

  A = 2π·2.49937·(2.49937 +12) ≈ 227.698 . . . . cm²

About 228 cm² of aluminum are required to make a typical soda can.

Line segment AB has endpoints A(1, 4) and B(2, 8) . A dilation, centered at the origin, is applied to AB¯¯¯¯¯ . The image has en
kumpel [21]
To determine the scale factor of the dilation, we determine the distances between the endpoints of the two lines through the equation,
                            d = √(x₂ - x₁)² + (y₂ - y₁)²
 Substituting the known values.

Line Segment 1:     d = √(1 - 2)² + (4 - 8)²  = 4.123

Line Segment 2:     d = √(18 - 14)² + (12 - 1)² = 11.70

Dividing the answers will give us 0.352

leva [86]

Answer:

$9,000.00 is her original investment worth in 10 yrs.

5000 x 1.08 ^10 = 10794.6249864

Then subtract -500000 = 5794.62498636

Step-by-step explanation:

Why, because the first year is proved 5000 x 0.08 = 400

= 400 year 1 but cna keep only if stays in investment for 10 years

400 x 10 = 4000 interest on investment

5000+ 4000 = $9,000.00 SI

+ 1,794.62 Interest on interest if applies (this is called CI) and makes $10794.62
