The height of cylinder a is 32 feet and the height of a cylinder b is 24 feet . If the cylinders are similar , find the surface

area ratio of cylinder a to cylinder b

Answer:

The surface area ratio of cylinder a to cylinder b is \frac{16}{9}

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its surface areas is equal to the scale factor squared

The scale factor is equal to the ratio of its corresponding sides

so

Let

z------> the scale factor

x------> surface area of cylinder a

y------> surface area of cylinder b

z^{2}=\frac{x}{y}

step 1

Find the scale factor

z=\frac{32}{24}=\frac{4}{3}

step 2

Find the ratio of the surface areas

z^{2}=\frac{x}{y}

we have

z=\frac{4}{3}

substitute

(\frac{4}{3})^{2}=\frac{x}{y}

\frac{x}{y}=\frac{16}{9}

Answer:

A: Corresponding

B: Alternate interior

C: Corresponding

D: Alternate exterior

E: Same side interior

Step-by-step explanation:

A: One angle is on the interior and one is on the exterior and they are both on the same side of the transversal which makes them corresponding angles

B: Both are in the interior just on opposite sides of the transversal

C: See answer to A

D: Both are on the exterior and they are on opposite sides of the transversal which makes them alternate exterior

E: Both are on the interior on the same side of the transversal which makes them same side interior.

Tan 235° = 2tan20°+ tan215°​
Mariulka [41]

Given :  tan 235 = 2 tan 20 + tan 215

To Find : prove that

Solution:

tan 235 = 2 tan 20 + tan 215

Tan x = Tan (180 + x)

tan 235 = tan ( 180 + 55) = tan55

tan 215 = tan (180 + 35) = tan 35

=> tan 55 = 2tan 20 + tan 35

55 = 20 + 35

=> 20  = 55 - 35

taking Tan both sides

=> Tan 20 = Tan ( 55 - 35)

=> Tan 20  = (Tan55 - Tan35) /(1 + Tan55 . Tan35)

Tan35 = Cot55 = 1/tan55 => Tan55 . Tan35 =1

=> Tan 20  = (Tan 55 - Tan 35) /(1 + 1)

=> Tan 20  = (Tan 55 - Tan 35) /2

=> 2 Tan 20  = Tan 55 - Tan 35

=> 2 Tan 20 +  Tan 35 = Tan 55

=>  tan 55 = 2tan 20 + tan 35

=>  tan 235 = 2tan 20 + tan 215
