Find the area of a circle with a circumference of 3.14 units

Nadusha1986 [10]

ANSWER 0.784602

If the circumference of the circle is equal to 3.14 units, to find the area

The area of a circle can be calculated using the diameter or the radius with two different formulas: A = πr2 or A = π(d/2)2, where π is the mathematical constant approximately equal to 3.14,r is equal to the radius, and d is the diameter.

What is the value of y in the solution to the system of equations? *x+3y=1 2x – 3y = -30

Delvig [45]

Answer:

$\large\boxed{y=\dfrac{32}{9}}$

Step-by-step explanation:

$\underline{+\left\{\begin{array}{ccc}x+3y=1\\2x-3y=-30\end{array}\right}\qquad\text{add both sides of the equations}\\.\qquad3x=-29\qquad\text{divide both sides by 3}\\.\qquad x=-\dfrac{29}{3}\\\\\text{put the value of x to the first equation}\\\\-\dfrac{29}{3}+3y=1\qquad\text{multiply both sides by 3}\\\\3\!\!\!\!\diagup^1\cdot\left(-\dfrac{29}{3\!\!\!\!\diagup_1}\right)+(3)(3y)=(3)(1)\\\\-29+9y=3\qquad\text{add 29 to both sides}\\\\9y=32\qquad\text{divide both sides by 9}\\\\y=\dfrac{32}{9}$

Please help it's urgent

ira [324]

Answer:

no solutions exist

Step-by-step explanation:

You can rewrite the denominator as:

-2(2x-6) so the equation becomes:

$-\frac12 \cdot \frac{2x-6}{2x-6} > 0$

from which you can see that not only should x ≠ 3, but for all values of x≠3 the equation is false.
