The formula for area of a circle is :

Area = pi x radius^2


Radius is half the diameter.

Radius = 38/2 = 19 kilometers


Area = 3.14 x 19^2

Area = 1,133.54 square kilometers

How do you answer this equation?<br> 5a - 12 = 48
IgorC [24]
Add 12 to both sides resulting in 5a = 60 and then divide both sides by 5 which results in a = 12 so your answer will be a = 12

Find a 3 by 3 magic square using numbers 2,5,8,12,15,18,22,25,29
Oksi-84 [34.3K]
I could not get it to work with all of those numbers. The only number that caused an issue was 29. I used 28 instead and it worked. I'm not sure if 29 was a typo, but I couldn't get 29 to work.

Given: (↔AB) ║ (↔CD)
nordsb [41]
1) m = y2 - y1/x2 - x1
y = mx + b
m = 7 - 0/3 - 8
y = -7/5x + 11.2
2) y= -7/5x + 12
(the slope or m stays the same because the two equations are parallel)
