The edges of it so 16 is the answer.
<span>Hello : let
A(-10,-3) B(7,14)
the slope is : (YB - YA)/(XB -XA)
(14+3)/17) = 1
an equation is : y=ax+b a is a slope</span>
y = x +b
the line F through point B(7,14) :
14 =7+b<span>
<span>b = 7
the equation is : y =X+7</span></span>
<span>the x- intercept of F when y=0 : x+7 =0 so : x = - 7 </span>
You will find the area of the semicircle by finding the area of the circle with a radius of 8.5 mm and the dividing it by 2.
A = pi x r^2
3.14 x 8.5^2
A = 226.865 square mm
226.865/2
113.43
The approximate area of the semi circle is 113.43 mm².
