Remark
The circumference of a circle is 2*pi*r. The angle the radius will move through is 360 degrees if the radius swings away from it's starting point and goes around the circle until it winds up back at its starting point. If it only goes part of the way, (in this case 165 degrees), then the circumference formula has to be modified.

Formula
Arc Length = (given central Angle/ 360) * 2 * pi * r is the partial distance around the circle.

Sub and solve
Arc length = (165/360) * 2* pi * r
Arc length = (165/360) * 2 * pi * 3
Arc length = 11/24 * 6 * pi
Arc length = 66/24 * pi What you do from here depends on what you have been given. This is one answer.

Another is 8.64 using 3.14 for pi. Please list your choices if there are any. If it is your custom to give out Brainliests, give it to the other responder. I forgot the 2 and had to edit it.

Find the exact distance between the line 6x-y=3 and the point (6,2). Show your work. Explain your answer.

Serggg [28]

Answer:

The distance of point ( 6 , 2 ) from line 6 x - y = 3 is $\frac{31}{\sqrt{37} }$ unit .

Step-by-step explanation:

Given as :

The equation of line is 6 x - y = 3

And The points is ( 6 , 2 )

Let The distance between the line and points is d unit

So, The distance of point from the line = $\frac{\begin{vmatrix}ax & +b y & + c\end{vmatrix}}{\sqrt{a^{2}+b^{2}}}$

Or, d = $\frac{\begin{vmatrix}6\times x & +(-1)\times y & + (-3)\end{vmatrix}}{\sqrt{6^{2}+(-1)^{2}}}$

Or, d = $\frac{\begin{vmatrix}6\times 6 & +(-1)\times 2 & + (-3)\end{vmatrix}}{\sqrt{6^{2}+(-1)^{2}}}$

Or, d = $\frac{36 - 2 - 3}{\sqrt{37} }$

∴ d = $\frac{31}{\sqrt{37} }$ unit

Hence The distance of point ( 6 , 2 ) from line 6 x - y = 3 is $\frac{31}{\sqrt{37} }$ unit . Answer

On Monday a stock sold for $12 a share at closing. On Tuesday the selling price for the stock was down $3 a share at closing. On

Anika [276]

Answer:the price of the stock at closing on Wednesday is $10

Step-by-step explanation:

On Monday a stock sold for $12 a share at closing. On Tuesday the selling price for the stock was down $3 a share at closing. This means that the amount at which the stock sold a share at closing on Tuesday is 12 - 3 = $9

On Wednesday the price of the stock at closing was up $1 from Tuesday. This means that the amount at which the stock sold a share at closing on Wednesday is

9 +1 = $10

Solve for a: <br> 3/5a = 1/4

liberstina [14]

3/5a = 1/4....multiply both sides by 5/3, cancelling out the 3/5 on the left
a = 1/4 * 5/3
a = 5/12
