Answer:
7
cm²
Step-by-step explanation:
First, find the area of the big circle with the formula A = r²
A = (3)²
A = 9
Now, we can find the areas of the smaller circles. Since they have the same radius, they are congruent (will have the same area)
A = r²
A = (1)²
A =
Now, we will subtract the areas of the smaller circles from the area of the big circle to find the area of the shaded region:
9 - - = 7
So, the area of the shaded region is 7 cm²
1 meter = 100 centimeters
16*100 = 1600 cm
1600/70 = 22.86
The largest number of fence posts that can be possibly cut from the log is 22.

Answer:
45 sides
Step-by-step explanation:
A regular polygon with an interior angle of 172
degrees has a total of
n 172 degrees
. So we have
n
*172
=
(
n
−
2
)
180
. Solving for n we have n
=
45
