Answer:
10π
Step-by-step explanation:
A = πr^2
C = 2πr
= 5- 5 = r
- 2 * 5 = 10
- C = 10π
Hello from MrBillDoesMath!
Answer:
The average is increased by 5
Discussion:
Let x be one number and y the other number.
Average of x,y = (1/2) ( x + y)
if, say, x is increased by 10 then the average of the numbers is
( ( x+ 10) + y) /2
= (x+y)/2 + 10/2 => (x+y)/2 is the average of the original numbers
= (x+y)/2 + 5
So the average is increased by 5
Thank you,

Answer:
P = 36 inches
A = 81 inches ^2
Step-by-step explanation:
This is a square so all the sides lengths are equal
P = 4s where s is the side length
P = 4*9 = 36 inches
A = s^2 where s is the side length
A = 9^2 = 81 inches ^2
Answer:
2=k^1/x
3=k^1/y
12=k^1/z.......we get...
(atq)------k^1/x=k^1/y=k^1/z
(*a^m=b^m......b=a)
~1/x=1/y=1/z
1/z=1/y+1/x×2
(12=3+2×2)
1/z=1/y+2/x.....proved
