general equation of circle is:

(x-x_1)^2+(y-y_1)^2=r^2

so centre is (0,0) and radius is

\sqrt{ \frac{9}{2} }

∴ PV = k    where k is constant

<span>The  pressure is 84 Pa at a volume of 36 L.

If the volume is expanded to 216 L, what will the new pressure be?
We need to find P  at  V = 216
From the equation (1) ⇒⇒⇒ PV = 3024
substitute with V = 216
∴ 216 P = 3024
∴ P = 3024/216 = 14 

The correct answer is option <span>B. 14 Pa</span>

Answer:

Area: 28.26ft², Circumference: 18.84ft

Step-by-step explanation:

Area of a circle: πr²

Circumference of a circle: πd (or 2πr)

Since the diameter is 6ft, then the radius is half of that, which is 3ft. This means that our area is:

πr²

π(3)²

π(9)

9π

9(3.14)

28.26ft²

Our circumference is:

πd

π(6)

6π

6(3.14)

18.84 ft
