Answer:
A = 9 pi cm^2
Step-by-step explanation:
Circumference = 2 * pi *r
6pi = 2 * pi *r
Divide each side by pi
6 = 2r
Divide by 2
6/2 = 2r/2
3=r
Now we want to find the area
A = pi r^2
A = pi (3)^2
A = 9 pi cm^2
It is a pattern so 2*3=6
3 times 4 is 12
4 times 5 is 20
5 times 6 is 30
6 times 7 is 42
so, 9 times 8 is 72.

Answer:
Multiply each side by −5, add 25 to each side
Step-by-step explanation:
-1/5(x-25) = 7
Multiply each side by -5/1 to clear the fraction
-5/1* -1/5(x-25) = 7*-5/1
x-25 = -35
Then add 25 to each side
x-25+25 = -35+25
x = -10
Answer:
both these equations are the examples of associative property.
#1 is the example of associative property with respect to multiplication.
#2 is the example of associative property with respect to addition.
Answer:
non of these choices I guess
