Answer:
8600 is 100 less
3440?
Step-by-step explanation:
Let's start with the area of the square

now let's subtract the are of the two half circles.
two half circles are the same as one circle, and we know that the diameter of the circle is 8 (same as the side of a square) so it's radius is 8/2= 4 inches

now we just subtract and our answer is
4(x+7) becomes 4x+28 you multipli the 4 in parentheses ans 2(x+7) becomes 2x+14
4x+28=2x+14 you move the x termes to the left and other numbers to the right look:
4x-2x=14-28 when you change the sides always change the sign +or-
2x=-14
2x/2=-14/2
X=-7
Answer: = 1whole

Answer:
2684
Step-by-step explanation:
flower bed - diameter: 20 meters
sidewalk: width: 3 meters
Total diameter: 23
Total radius: 16.5
Area Equation:
16.5 x 3.14 ^2
51.81 ^2
= 2684.2761
~ 2684
