Generally, when finding the circumference of a circle, then formula is c=2*3.14*r (where r is the radius)

Substitute the given values

408.2= 2*3.14*r

R is 65

Now that we know that the radius is 65, the formula for the area of a circle is a=3.14*r^2

Substitute the given values

3.14*65^2

Therefore, the area of the circle is 13266.5 metres squared

Answer:

70.5°

Step-by-step explanation:

Use the law of sines.

$\frac{Sin 45}{4.5}=\frac{sin x}{6}$

Multiplying both sides of the equation by 6 will result

$sin x = 0.942809....$

Then just use the inverse sine function on your calculator

$sin^{-1}sinx=sin^{-1}0.942809...$

$x=70.5$
