Which formula can you use to find the radius (r)r if you know that C=2πr?

1 answer:

3 0

First of all, it is 2r $\pi$ and it would be divide by 3.14 (pi) and then you should have the diameter. Then divide by 2 to find radius.

Answer: 11.2x -9.6

Step-by-step explanation:

7.2(x + 3) + 4(x - 3) - 12 - 7.2* (x + 3) + + 4*(x - 3) then

7.2x + 21.6 + 4x - 12 - Combining like terms 7.2x+ 4x and numbers + 21.6- 12

7.2x + 4x +21.6 -12 Then we have

11.2x -9.6

Find the missing values of the variables. The diagram is not to scale. Show steps

earnstyle [38]

Step-by-step explanation:

i assume this is the question you asked me to look at.

Well, angle 116° and y are supplementary angles

therefore,116°+y=180°

y=180°-116°=64°

Now to find x

x+y+125+72=360°

x+64+125+72=360

x+261=360

x=360-261=99°

Answer:

$26 \frac{1}{4}$

Step-by-step explanation:

First we turn them into improper fractions

$-\frac{7}{2}(-\frac{45}{4})$

then we multiply it

$-\frac{7}{2}*-\frac{45}{4}=\frac{315}{12}=26\frac{1}{4}$
