find the circumference and the area of the circle with the radius 9m use the value 3.14 for it do not round your answer be sure

kirill [66]

Explanation:

The circumference and the are of a circle with radius r

are:

$\begin{gathered} A=\pi r^2 \\ C=2\pi r \end{gathered}$

If we use pi = 3.14 and the radius is 9m:

$A=3.14\cdot(9m)^2=3.14\cdot81m^2=254.34m^2$ $C=2\cdot3.14\cdot9m=56.52m$

Answers:

• Area: ,254.34 m²

• Circumference: ,56.52 m

3(12x – 9) + 9 = 2x + 4 Would this be infinite solution, one solution or no solution?

timama [110]

Answer:

One solution

Step-by-step explanation:

Let us first expand the left side of the equation to rid of the parenthesis:

$3*12x-3*9+9=2x+4\\36x-27+9=2x+4\\36x-18=2x+4$

Now let us isolate the variable to sove for x:

$36x-2x=4+18\\34x=22\\x=\frac{22}{34}\\x=\frac{11}{17}$

Therefore, x= $\frac{11}{17}$ . As you can see, there is just one solution.

I hope this helps! Please let me know if you have any further questions :)

What is the combined weight of all the kittens

Aleksandr [31]

The answer is 5. If you do 3/8 x 4 you get 1.5, if you multiply 1/2 x 3 you get 1.5, if you do 1/4 x 3 you get .75 and if you do 5/8 x 2 you get 1.25. So, 1.5 + 1.5 + .75 + 1.25 = 5
