Use the formula (n - 2) * 180 to find the sum of the interior measures of a polygon.
n stands for the number of sides that the polygon has, so substitute 10 for n since a decagon has 10 sides.
(10 - 2) * 180, start by solving inside the parentheses and subtracting 10 and 2.
(8) * 180, multiply.
B. 1,440 is your answer.
X and y vary inversely:
y=k/x
y=8/3 when x=8
8/3=k/8
Solving for k:
8(8/3)=k
64/3=k
k=64/3
y=k/x
y=(64/3)/x
y=(64/3)(1/x)
y=64/(3x)
when x=4→y=64/(3x)=64/(3(4))→y=16/3
Answer: Second Option y=64/(3x); 16/3

Answer:
1. 18.84 in
2. 56.52 cm
Step-by-step explanation:
The circumference of a circle is the distance around the circle. Its found using the formula C = πd or C=2πr. The variable d represents the diameter or the distance from one edge of the circle to the other through the cent. The variable r represents the radius of a circle or the distance from one edge to the center. Use the formula by substituting a diameter or radius then simplify.
1. C = πd = π(6) = 3.14(6) = 18.84 in
2. C = 2πr = 2(3.14)(9) = 56.52 cm
