1.) D = 2pi * d * A / 360 degrees; Where:
pi = 3.14;
d = distance or 56,000,000 km (5.6x10^7 to standard notation)
A = angular size in degrees or .00688 degrees (.00012 radian to degrees)
D = 2(3.14) * 56,000,000 * .00688 / 360
= 6.28 * 385,280 / 360
= 2,419,558.4 / 360
D = 6,720.996 or 6,721
Therefore, 6,721 km. is the approximate diameter of Mars.

Answer:
y = -5
x = 2
Step-by-step explanation:
The computation is show below:
Given that
-6x - 6y = 18
6x - 3y = 27
Now if we solved both equation so
-9y = 45
y = -5
And, x is
-6x - 6(-5) = 18
-6x + 30 = 18
-6x = 18 - 30
-6x = -12
x = 2
