First let's get rid of the parenthesis:

12 - 4x + 3x = 4 + 10 + 2x

Now group the x's on the left and the numbers on the right

-4x + 3x - 2x = 4 + 10 - 12

...and simplify

-3x = 2

divide by -3 to isolate x

x = -2/3

Consider a circle that has a circumference of 28/3.14 centimeters. What is the area of this circle? Answer fast plz also can you
bija089 [108]

Answer:

A=6.33\ cm^2

Step-by-step explanation:

step 1

Find the radius of the circle

we know that

The circumference of a circle is equal to

C=2\pi r

we have

C=\frac{28}{3.14}\ cm

\pi=3.14

substitute the values

\frac{28}{3.14}=2(3.14)r

r=\frac{28}{19.7192}\ cm

r=1.42\ cm

step 2

Find the area of the circle

The area of the circle is equal to

A=\pi r^{2}

substitute the values

A=(3.14)(1.42)^{2}

A=6.33\ cm^2
