Answer:
706.858 inches^2
Step-by-step explanation:
Calculate radius = d/2 = 30/2 = 15in.
Calculate area = 3.142×radius^2
=3.142×(15)^2
=706.858 inches

Answer:
c
Step-by-step explanation:
rearrange:
3x-4y=24
-4y=-3x+24
y=-3/-4 x + 24/-4
y= 3/4 x -6
Answer:
62
Step-by-step explanation:
Draw a line from the bottom of the 4 foot line straight across (horizontally) until it hits the vertical line on your left.
The two lines (the one you drew and the left vertical line) meet at right angles.
The upper figure is a rectangle.
Area = L * W
L = 5
W = 4
Area = 5 * 4
Area = 20
Now the bottom rectangle can be found the same way.
Area = L * W
L = 14
W = 3
Area = 14 * 3
Area = 42
The total area = 42 + 20
Total area = 62.
The comment was correct.
3x + 3y = 27
3x - 3y = -11
------------------add
6x = 16
x = 16/6 which reduces to 8/3
3x + 3y = 27
3(8/3) + 3y = 27
8 + 3y = 27
3y = 27 - 8
3y = 19
y = 19/3
solution is (8/3, 19/3)
