Given that area of circle is 64cm we can assume we will need to first find radius and then calculate circumference.
First we know that area of a circle is 
hence 
We can now put in our area,
Then we use the formula for circumference,
Hope this helps.

Answer:
x = 8
Step-by-step explanation:
3x - 5 = 2.5x + 3 - (x - 4)
<em>open parentheis</em>
3x - 5 = 2.5x + 3 - x + 4
3x - 5 = 1.5x + 7
<em>subtract 1.5x from both sides of the equation</em>
3x - 1.5x - 5 = 7
1.5x - 5 = 7
<em>add 5 to both sides of the equation</em>
1.5x = 7 + 5
1.5x = 12
<em>divide both sides of the equation by 1.5</em>
1.5x/1.5 = 12/1.5
x = 12/1.5
x = 8
