Answer:

Exact circumference is $7\frac{49}{150}km$

Approximate circumference is $7.33 km$

Step-by-step explanation:

We are given;

The diameter of a circle as $2\frac{1}{3} km$

We are required to determine the exact and approximate circumference of the circle.

We know that the circumference of the circle is given by;
Circumference = πD, where D is the diameter

Taking π as 3.14

$Circumference=3.14 (2\frac{1}{3}km)$

$=7\frac{49}{150}km$

The exact circumference of the circle is $7\frac{49}{150}km$

$7\frac{49}{150}km=7.327 km\\ = 7.33 km (nearest hundredth)$

Thus, the approximate circumference of the circle is $7.33 km$

In the diagram, the radius of the outer circle is 2x cm and

hodyreva [135]

Area shaded = Area big circle- Area of small circle;

200 pi= pi•(2x)^2 -pi•6^2;

200pi= pi•4x^2 -pi•36;

200pi=pi•4(x^2 -9) divide both sides by 4pi;

50=x^2 -9; So x=sqrt(59)~7.68cm
