Geometry! ! which description best describes the three-dimensional object that is formed when the shape is rotated about the axis as shown? a). a hollow cylinder b). a cylinder with an open top c). a rectangular prism with an open top d). a cube

The three-dimensional figure that is obtained on when the shape is rotated about the axis as shown is:

B) A cylinder with an open top

Step-by-step explanation:

When we rotate the given figure around the given axis than we will get a three dimensional figure with a circular base and a open top since there is no 2-d side given for the top and the surfaces are curved .

Hence, the figure so obtained is a cylinder with an open top.

Hence, option (B) is the correct option.

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
