Answer:

radius=11.5

diameter=23

Step-by-step explanation:

The volume of a sphere is V=4/3 Pi r^3

We can use this to solve for the radius.

555.4= 4/3 (3.14)r^3

Solve for r how you would any other equation. Multiply 4/3 and 3.14.

555.4=4.187 r^3

Divide both sides by 4.187

132.65=r^3

To get rid of the ^3, find the cube root of both sides on a calcualtor.

r= 11.5

The diameter is the radius time two.

11.5 (2)=23.

Hope this helps!

Note: When I say both sides, I mean both sides of the = sign.

Answer:

$226

Step-by-step explanation:

1. define the variable x

x = # of days to rent the carpet cleaner

2. substitute x for 7 days

c(7) = 30(7) + 16

3. solve

c(7) = 210 + 16

c(7) = 226

For 7 days, Rhonda will have to rent the carpet cleaner for $226.

LiRa [457]

The answer is -52

First you must substitute the variables

$(3^2)(-4)-(-4^2)$

Then you must simplify

$-52$

Help me with this one problem please :( <br> Find the following arc measures.

r-ruslan [8.4K]

Answer:

Arc KL $=23$

Arc OM $=113$

Step-by-step explanation:

We know that Angle NPM is equal to 90 degrees.

Therefore, Angle KPM is also equal to 90 degrees.

We are told that Arc LM is equal to 67.

Thus, the measure for Arc KL is equal to $90-67=23$

We also know that Angle OPN is equal to Angle KPL.

Therefore, the measure of Arc ON $=23$

Using that information, we know that Arc OM is equal to $90+23=113$

Hope I helped!
