Area of a circle= $\pi *r*r$

For radius(r)=8 km

The area of the circle is :

= $\pi *8*8$

As:

$\pi =\frac{22}{7}=3.14$

Area of the circle:

$=3.14*8*8\\\\=3.14*64\\\\=200.96km^2$

0.5x -2 = 1.5x + 0.15

frutty [35]

Answer: x=−2.15

Step-by-step explanation : Alright Let's solve your equation step-by-step.

0.5x−2=1.5x+0.15

Step 1: Subtract 1.5x from both sides.

0.5x−2−1.5x=1.5x+0.15−1.5x

−x−2=0.15

Step 2: Add 2 to both sides.

−x−2+2=0.15+2

−x=2.15

Step 3: Divide both sides by -1.

−x

−1

2.15

−1

x=−2.15<em> hope this helped!- Alex</em><u> </u>
