Answer: a semicircle is half the perimeter (or circumference) of its full circle, so the full circle here has a circumference of 20.56
Use that to figure out the length of the radius: Circumference divided by 2(pi) will give you the radius.
Once you have the radius, use the formula for Area of a Circle: A = pi * radius2.
Once you have the area of the circle, divide that by 2 to get the area of the semicircle.
π=3.14 C=3.14 x 8cm C=25.1cm Divide by 2 for the semicircle 12.5 Add the diameter (8cm) 12.55+8=20.5
I thought that was all one equation lol this is very simple just plug in -3 for x
which is -3^2-3 which is -12
The slope is 4 ok bro bro
0.6 x 12.9 = 7.74
Hope this helps!
