(x-h)^2 + (y-k)^2 = r^2
(h,k) is the center
r is the radius
This is given in your lesson plan or textbook.
Answer:
B,C,E
Step-by-step explanation:
Add the first number with itself and it will need to equal the second one
So 5+5 would equal 10, 5/10 is basically this
Answer:

Step-by-step explanation:
If you want find the perimeter, then you must add all lengths of sides of the given polygon.

Other method.
Convert the mixed numbers to the decimal:

Because 17 - 14 = 14 - 11 = 3, the ratio of the arithmetic series is 3;
Then, A4 = 8 - 3 = 5; A3 = 5 - 3 = 2; A2 = 2 - 3 = -1; A1 = -1 - 3 = -4.
But 68 = A1 + ( n- 1 ) x r;
68 = -4 + ( n - 1) x 3;
( n - 1 ) x 3 = 72;
n - 1 = 24;
n = 25;
Finally, Sn = ( A1 + An) x n / 2; then, S25 = ( - 4 + 68) x 25/2;
S25 = 64 x 25 / 2;
S25 = 32 x 25;
S25 = 800;
The value of sum is 800.
Length of the arc = 1/2 πD = 1/2 x 3.14 x 6 = 9.42 yd
Perimeter = 9.42 + 6 + 6 + 6 = 27.42 yd

Answer: 27.42 yd
