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.

A town has a population of 5000 and grows at 4% every year. To the nearest year, how long will it be until the population will r

Rus_ich [418]

Answer:

About 21.457 years

Step-by-step explanation:

You can solve this by setting up a simple equation.

$5000\cdot 1.04^x \geq 11600$

$1.04^x \geq 2.32$

log base 1.04 2.32=x

$x\approx 21.457$ years

Write the following in the ratio form a) 0.5 b) 0.6 c) 1.25 d) 3.4

alex41 [277]

Answer:

A) 1:2

B) 3:5

C) 5:4

D) 17:5

Step-by-step explanation:

Step 1) Convert the decimal number to a fraction

Step 2) Multiply the numerator and denominator by 10 to eliminate the decimal point.

Step 3) Simplify the fraction in the previous step by dividing the numerator and the denominator by the greatest common factor (GCF)

Step 4) Convert the fraction in the previous step to a ratio by replacing the divider line with a colon

Heres an example. I'll do the last one.

3.4 = 3.4/1

(3.4 x10) /(1 x 10)= 34/10

34 /2 = 17

10/2 = 5

17/5 = 17:5
