Answer:
1 4/45
Step-by-step explanation:
15 times 10^8 is the answer
The circumference of a circle has the formula: 2*pi*r. So, we could easily determine the value of r.
C = 2*pi*r
12*pi = 2*pi*r
12 = 2r
r = 12/2
r = 6 inches
Knowing the r, we could find the area which has the formula
A = pi*r^2
A = pi*6^2
A = 113.1 square inches
Hope this helps!
2y + 2x = 6
2y - x = 12
Subtract
3x = -6, x = -2
2(-2) + 2y = 6
-4 + 2y = 6
2y = 10, y = 5
Final solution: x = -2, y = 5
I tried my best to explain it...dm me if you still don’t understand
Hope this helped :)
