Answer:

1st cylinder: 3541.9 square mm

2nd cylinder: 439.6 square cm

Step-by-step explanation:

s = 2\pi r^{2} + 2\pi rh\\s = 2(3.14)(12)^{2} + 2(3.14)(12)(35)\\s = 6.28(144) + 6.28(420)\\s = 904.32 + 2637.6\\s = 3541.92\\s = 3541.9

Second cylinder.

s = 2\pi r^{2} + 2\pi rh\\s = 2(3.14)(7)^{2} + 2(3.14)(7)(3)\\s = 6.28(49) + 6.28(21)\\s = 307.72 + 131.88\\s = 439.6

Agata [3.3K]

Answer:

 32 Roller Coasters

Step-by-step explanation:

There are a total of 112 rides in Cedar Point.

\frac{2}{7} of these rides are roller coasters.

In Algebraic Word Problems, the term "OF" means Multiplication.

Number of Roller Coasters = \frac{2}{7} of 112

                                          =\frac{2}{7} X 112

                                          =2 x 16

                                          =32

There are 32 Roller Coasters in Cedar's point's collection of rides.

2. Find tan A for the right triangle below:
Andreyy89

Answer:

tan A=\frac{8}{15}

Step-by-step explanation:

According to the trigonometric ratios the tangent of an angle is the ratio of perpendicular to base, i.e.

tan\theta=\frac{Perpendicular}{Base}

In the provided triangle the perpendicular is 8 and base is 15.

Compute value of tan <em>A</em> as follows:

tan\theta=\frac{Perpendicular}{Base}\\tanA=\frac{8}{15}\\

Thus, the value of tan <em>A</em> is \frac{8}{15}.
