Answer:
173.01
Step-by-step explanation:
To area of a sector or portion of a circle is found using:
Substitute N = 50 and A = 27.93.
It becomes 
The area of the entire circle is 200.94. The area of the blue part of the circle can be found by subtracting the red section from the entire circle.
200.94 - 27.93 = 173.01
$12.80
Explanation:
3=$2.40 3\2.40 =0.80 0.80 • 16 = $12.80
Complimentary angles, when added, will equal 90 degrees
so < DFG and < JKL, when added = 90
x + 5 + x - 1 = 90
2x + 4 = 90
2x = 90 - 4
2x = 86
x = 86/2
x = 43
< DFG = x + 5......43 + 5 = 48 degrees <==
< JKL = x - 1........43 - 1 = 42 degrees <==
What is 40/100 as a decimal?
To write 40/100 as a decimal you have to divide numerator by the denominator of the fraction.
We divide now 40 by 100 what we write down as 40/100 and we get 0.4
