Answer:
12
Step-by-step explanation:
We can use the pythagorean theorem giving us:
a^2+b^2=c^2
(6sqr2)^2 + (6sqr2)^2 = c^2
72+72=c^2
144=c^2
12=c
Answer:
Let R be the greater radius and r be the smaller radius
A) Area of the sidewalk = R^2 - r^2 - This can be the expression
B) = 3.14
=(R^2-r^2)
=(11^2-9^2)
=(121-81)
=*40
That was the simplified expression
Answer = 3.14 * 40 = 125.6m^2

.
In point 2, the statement is False.
In point 3, the statement is true
.
In point 4, the statement is False.
F(x) = 2x^2 - x
if x=-3
f(-3) = (2*(-3)^2) - (-3)
f(-3) = (2*9) + 3
f(-3) = 18 + 3
f(-3) = 21
