The area of the considered composite figure is given by: Option: 6π + 16 cm²
<h3>How to calculate the surface area of a composite figure?</h3>Surface area are derived for some standard shapes like circle, triangle, parallelogram, rectangle, trapezoid, etc.
When some shape comes which isn't standard figure, then we find its area by slicing it (virtually, like by drawing lines) in standard shapes. Then we calculate those composing shapes' area and sum them all.
Thus, we have:
That ∑ sign shows "sum"
For this case, the missing image is attached below.
As visible, the area of the figure = Sum of area of those 3 semi circles + Area of that square(its square because it has 4 equal sides in which adjacent sides are perpendicular) in between.
The side of the square is of 2+2=4 cm( as half of its side is 2 cm), thus, Area of that square = 4² = 16 cm²
All those 3 semicircles has radius = 2 cm
Since radius is same, so area of those 3 semicircle is same =
Thus, we get:
Area of the composite figure =

The given function
Since x = 1 is one of its zeroes, then we will use it to find the other zeroes
The factor is x - 1
Use the long division to find the other factors
Divide 2x^3 by x, then multiply the answer by (x - 1)
Subtract the product from the original equation
Now, divide -3x^2 by x, then multiply the answer by (x - 1)
Subtract it from the denominator of the fraction
Divide -9x by x and multiply the answer by (x - 1)
Subtract it from the numerator
Then we will factor this trinomial into 2 factors
Equate each factor by 0 to find the other zeroes of the equation
The zeroes of the equations are 1, 3, -3/2
The solutions of the equations are
