First do, 3.14 x 20 ^ 2
3.14 x 20 ^ 2 = 1,256
Then do, 1,256/4
1,256/4 = 314
Why 4?
This part of the circle is 1/4 of the entire circle.

5b)36-8=28
28+2 = 30
Ok...
5.6 = 56/10 = 560/100

So, the answer is:
100You could multiply both sides of the equation by 100 to get the value of (j) quickly.
Answer:
-11
8 = 2x + 30
8 - 30 = -22
-22 ÷ 2 = -11
x = -11
Also if you place 2×(-11) + 30 you get 8
