The radius of a circle is 1 inch. What is the area?

r=1 in

The formula for the area of a circle is given as:

πr²

The radius (r) = 1 inch

Hence,

Area of the circle = π × 1²

= 3.1415926536 square inches

Approximately = 3.14 square inches or we can say that the Area of the circle = π square inches

Answer:

x = -33

Step-by-step explanation:

2/3(x+6)=-18

Multiply each side by 3/2

3/2*2/3(x+6)=-18*3/2

x+6 = -27

Subtract 6 from each side

x+6-6 = -27-6

x = -33

$625 \geqslant 60x + 300$

$325 \geqslant 60x$

$5.41 \geqslant x$

But assuming integer hours only, round down to 5h. The cost will be $600.

Solve each system by substitution 2x + y = 20 and 6x - 5y = 12

ivolga24 [154]

$\huge\mathbf{Answer࿐}$

$\underline{ \underline{ \bf{step} - 1}}$

Taking first equation,

$2x + y = 20$

$y = 20 - 2x$

$\underline{ \underline{ \bf{step} - 2}}$

plugging the value of y in second equation,

$6x - 5y = 12$

$6x - 5(20 - 2x) = 12$

$6x - 100 + 10x = 12$

$16x = 12 + 100$

$x = \dfrac{112}{16}$

$x = 7$

$\underline{ \underline{ \bf{step} -3}}$

plugging the value of x in first equation,

$2x + y = 20$

$(2 \times 7) + y = 20$

$14 + y = 20$

$y = 20 - 14$

$y = 6$

<h2>Conclusion :</h2>

$x = 7$
$y = 6$
