Answer:

18.84

Step-by-step explanation:

Circumference = 2πd

where d = diameter

the shape given has a diameter of 6

to find the circumference we simply plug in the value of the diameter as well as π into the formula

formula : C = πd

π = 3.14 and d = 6

C = 3.14(6) = 18.84cm

22 people can arrest Allie’s birthday party.

c = 5p + 230
c = 340
340 = 5p + 230
340 - 230 = 5p + 230 - 230
110 = 5p
110/5 = 5p/5
22 = p

Factor completely 20x3y + 30x2y2.

Lana71 [14]

Hey!

It looks like you meant: $20x^3y+30x^2y^2$
Then, we are going to change the expression, specially the exponents. The reason behind this is because we don't want anything to be cubed. Here's an example: $\:a^{b+c}=a^ba^c$
$=20x^2xy+30x^2yy$
Factor out the common term, which is $10x^2y$
$=10x^2y\left(2x+3y\right)$
Done!

Let me know if you have any questions regarding this problem!
Thanks!
