Area of a FULL circle is founded by Pi multiplied by radius squared

But, in the figure, a semicircle is shown , so we change the formula so that it become Pi multiplied by radius squared divided by two ( because it is HALF of a circle)

We half the diameter in order to get the radius (44/2 is 22)

Pi multiplied by 22^2 divided by 2

Which is 760.27

Answer:

759.88 square inches

Step-by-step explanation:

r =  \frac{1}{2}d =  \frac{1}{2} \times 44 = 22 \\    \\ area = \frac{1}{2}  \pi \:  {r}^{2}  \\ area =  \frac{1}{2}  \times 3.14 \times 22 \times 22 \\ area = 759.88 \: square \: inches

How do i find the roots of this equation: f(x) = 2x5 - 9x4 + 12x3 - 12x2 + 10x - 3 = 0
Fantom [35]
The equation is <span>f(x) = 2x5 - 9x4 + 12x3 - 12x2 + 10x - 3 = 0
remark:
the sum of coefficients is = 2-9+12-12+10-3=-7+7=0, so a=1 is a zero of f
f can be written as </span>f(x) = (x-1)Q(x), and f(x) / (x-1)= Q(x)
after euclid's division
Q(x) = 2x4 - 7x3 + 5x2 - 7x +3
so for finding the other roots, making Q(x) for product of factors is a must
