Give me the answer pls!

Square Area = ( one side length)²

784 = (AB)²

AB = 28

circle radius = 14

pi = 3.142

semi circle parameter = pi × r

= 3.142 × 14 = 43.988

square parameter = 3 × 28 = 84

we dont calculate the 4th side.

parameter of the figure = 43.988+ 84= 127.988

-4

step-by-step explanation:

(-4+8)=-(4-8)=-8+4=-4

no because after the troops were pulled many blacks were killed by hangings lynchings and other cruel ways which in a way interrupted the reconstruction of the south and differed from the way abraham lincoln had an idea of reconstruction
