Answer:

119.380521 in

Step-by-step explanation:

C= 2piR

C= 2xpixR

C= 2xpix19

C= 2x3.14x19

C= 6.28x19

C= 119.32

Which is approximately 119.380521

Mrrafil [7]

Step-by-step explanation:

$f(x) = \frac{1}{8} \times {5}^{x} \\ \\ \therefore \: f(2) = \frac{1}{8} \times {5}^{2} \\ \\ \therefore \: f(2) = \frac{1}{8} \times 25 \\ \\ \huge \red{ \boxed{ \therefore \: f(2) = \frac{25}{8} }}$

If tan x° = 6 divided by g and sin x° = 6 divided by h, what is the value of cos x°? cos x° = h divided by g cos x° = g divided

Westkost [7]

The value of cos x⁰ from the information given is; g/h.

<h3>What is the value of cos x⁰?</h3>

According to the task content;

The value of cos x° from the information contained in the task content is required.

From conventional Trigonometry;

It follows that tan x = sin x/cos x.

On this note, it follows that;

cos x⁰ = sin x⁰/tan x⁰.

cos x⁰ = 6/h ÷ 6/g

cos x⁰ = g/h

Ultimately, the value of Cos x⁰ by evaluation is g/h.
