Answer:
(A) Take half the area of the whole circle.
Step-by-step explanation:
A semi-circle is half of a circle, thus the area of circle is given by:'
Area of circle=
, where r is the radius of the circle.
Since, A semi-circle is half of a circle, therefore area of the semi circle is also half of the circle, therefore
Area of semi circle=
Thus, the area of the semi circle can be found by taking half the area of the whole circle.
Answer:
x² - 4x + 3 = 0
Step-by-step explanation:
given roots x = a and x = b then the corresponding factors are
(x - a) and (x - b)
the equation is then the product of these factors , that is
(x - a)(x - b) = 0
given
roots x = 3 and x = 1 , then factors are (x - 3) and (x - 1) , then
(x - 3)(x - 1) = 0 ← expand factors using FOIL
x² - 4x + 3 = 0
