Answer:

8.6 km

Step-by-step explanation:

The circumference of a circle is given in terms of its radius as ...

C = 2πr

Then the radius can be found from the circumference using ...

r = C/(2π)

Filling in the given values, we find the radius to be ...

r = (54 km)/(2·2.14) = (54 km)/6.28 ≈ 8.59873 km

The radius is about 8.6 km.

Sliva [168]

Answer:185 m , 60 m

Step-by-step explanation:

Given

Length is 5 m more than 6 times its width

Suppose width is $x$

So, length is given by $6x+5$

The area is given by $l\times b$

Put values of length and width

$\Rightarrow (6x+5)x=5550\\\Rightarrow 6x^2+5x-5550=0\\$

On solving the quadratic equation, we get $x=30$

Length is $6\times 30+5=185\ m$

Width is $x=30\ m$
