Answer:
=3.201x109
=4.85x103
Step-by-step explanation:
M(N+2)+3N+6
M*(n+2)+3(n+2)
Answer
(n+2)*(m+3)
1-(-4)^2
1-(-4 times -4)
1-(16)
1-16
-15
The answer would be (8pi +12) in^2
This is because to solve for the semicircle the equation is:
1/2*pi*r^2 1/2*pi*16
And the equation for the triangle is:
1/2*hb*h 1/2*8*3
