Which question and if you have the name of the assignment or it has a copy right at the bottom you can most likely find it online hope that helps
A≈21.46
First you find the area of the square
A=a^2 which is
=10^2
A=100
Then you find the area of the circle
A=πr^2
= π(5)^2
A≈78.54
Now you subtract the 78.54 from 100 to get 21.46
x^a / x^b = x^(a-b)
so here its x^( (5/6)- (1/6) )
= x^ 4/6 or ^2/3
1 x
---- = -----
8 1224
8x = 1224
x = 153
25% = 0.25
40 / 0.25 = 160
40 is 25% of 160.
