(+5) + (-8) = -3
That’s what I got.
Take the common denominator and divide by 3
Not getting in to too much details but basically
Area of half circle - area of triangle
3.14r^2-1/2bh
r=6 b=12 h=6
Answer:
a & d
Step-by-step explanation:
got them right om edge
It should be 3.25
S is half the perimeter, so .5*(7+5+10)=11
Plug in 11 and you get A=sqrt(264)
A also is half base times height
sqrt(264)=.5*10*h
h=sqrt(264)/5
h=3.25
