Answer:
1) 78.54
2) 490.87
3) diameter: 15.9999 so 16.00? circumference: 50.27
Step-by-step explanation:
11%=11/100
11/100=22/x
we have to solve for x now
11x=2200 divide by 11 both side
x=200
that the answer
D. right
a right angle always equals a right triangle
Answer:
Solution is 
Step-by-step explanation:
Given Differential Equation,
...............(1)
We need to solve the given differential equations using undetermined coefficients.
Let the solution of the given differential equation is made up of two parts. one complimentary solution and one is particular solution.

For Complimentary solution,
Auxiliary equation is as follows
m² - 2m + 1 = 0
( m - 1 )² = 0
m = 1 , 1
So,

Now for particular solution,
let 


Now putting these values in (1), we get






Therefore, Solution is
