Answer:

120°

Step-by-step explanation:

Set up a proportion of the circle circumference and angle to the arc length and central angle x:

\frac{18}{360} = \frac{6}{x}

Solve for x:

18x = 2160

x = 120

Measurement of the central angle of the arc is 120°

adoni [48]
A ratio reads left to right and can be written in 3 different ways. for example, 3:5, 3 to 5, or 3/5
if you have a problem that says something like: for every 3 people there is 1 child, the ratio is 3 to 1. Hope this was helpful in in 6th grade too and in advanced math!

What is the value of 4+(8*2)-3+5
Fed [463]
Hello there!

You have to do PEMDAS to solve this problem

Parentheses
Exponents
Multiplication
Division
Addition
Subtraction

We're doing: addition, parentheses , and multiplication!

So, 8(2) = 16, right?

Problem becomes: 4 + (16) - 3 + 5

4 + 16 = 20

Problem becomes: 20 - 3 + 5

20 - 3 = 17

17 + 5 = 22

So, therefore your answer would be: 22

Good luck on your assignment and enjoy your day!

Find the radius of a circle with an area of 529π square inches.
kifflom [539]

Answer:

Step-by-step explanation:

Given

Area (A) = 529\pi square inch

radius(r)  =?

Now

we have the formula

\pi r^{2} = area

\pi r^{2} = 529\pi

Both pie will be cancelled and we get

r^{2} = 529

r =\sqrt{529}

r = 23 inch

Hope it helped:)
