P = (2,-4)
Q = (3,9)
R = (-4,2)
rotation by 180 degrees means that the points are inverted. the answers would be the opposite of the given
Perimeter of the semicircle is the formula r(π+2).
Radius r=14 cm
So, perimeter =14(π+2)... where π= 22/7
=2(22+14)=44+28=72 cm
So , the answer is
72 I guess
4:2
