A square side is twice of the radius
sq side: 4 x 2
sq side: 8
find the area of the square.
A = b x h
A = (8) x (8)
A = 64
<em>Area of square is 64</em>
----------------------------------------------------------------------------------------------------------------
Find the area of the circle
Area of circle:
A = πr²
A = π(4)²
A = 16π
A = 16(3.14)
A = 50.24
----------------------------------------------------------------------------------------------------------------
Divide the circle from the total
50.24/64
50.24/64 = 0.785
0.785 = 78.5/100 = 78.5%
----------------------------------------------------------------------------------------------------------------
Subtract the circle's percentage from 100% (the total)
100 - 78.5 = 21.5
21.5% is your chance of not hitting a point in the circle.
-----------------------------------------------------------------------------------------------------------------
21.5%, or (B), is your answer

a.129.6+16.2
= 145.8
b.129.6×16.2
= 2099.52
c.129.6÷16.2
= 8
d.129.6−16.2
= 113.4
e.192.4+14.8
= 207.2
A²-5a+6
to factorise you find the common numbers that add to make 5 and times to make 6
soo that means it is
(a-2) (a-3)
only the last one since the others don’t pass the vertical line test
which is when you draw a straight line down your function and if it hits 2 or more points it is not a function
Slope: 3, y-intercept: 4, equation: y = 3x + 4
