The formula to find the circumference is pi*radius^2. Since your radius is 6371, the radius squared is 40589641 and that times pi is 127451473. That is your circumference

In order to find the circumference of a circle, you must use the formula c=2* $\pi$ *r.

Since you're already given the radius, all you have to do is use the formula and do 2 times 3.14 times 6371 and you get 40009.88 as your circumference.

Triangle FGH is similar to JKM.

Answer: J = 14.4 cm

Step-by-step explanation:

<em>K is similar to G</em>

So we can find the scale that FHG was dilated by dividing the side length of G by the side length of K

16.56/9.2 = 1.8

So the sides of the triangle KMJ were multiplied by a factor of 1.8

to find m :

25.92/1.8 = 14.4

J = 14.4
