If the circumference of a circle is 40 m, its area is 127.32395447352 m².
Answer:

Step-by-step explanation:
The similar triangles are drawn in the figure attached.
As shown in the figure, the smaller triangle ΔABC, and the larger triangle ΔA'B'C' share the same slope; therefore, the slope of the hypotenuse is the length of the triangle ΔA'B'C' divided by its base:

Therefore, the equation of the hypotenuse is

3/4 y= 24
Multiply both sides of the equation by 4/3 (the reciprocal of 3/4) to be left with y.
4/3 × 3/4y = 24 × 4/3
y = 24 × 4/3
y = 32

5 and 1 half this is the answer my son thought of.
Answer:
x = -12
Step-by-step explanation:
-2(10 + x) = 4
Divide each side by -2
-2(10 + x) / -2 = 4/-2
(10 + x) = -2
Subtract 10 from each side
10+x-10 = -2-10
x = -12
