First thing to know is that the quarter circle = 1/2 semi circle
Also note that the diameter of the semi circle is the other length for the rectangle
We want to add up the areas of the three things
Area of a circle is (3.14)r^2, but we have a semi circle so its (1/2) x (3.14)r^2, which is 56.52
The quarter circle is 1/2 x 56.52 = 28.26
Area of rectangle is h x l so 2 x 12 = 24
56.52 + 28.26 + 24 = 108.78
Hope this helps :)
Answer:
109
Step-by-step explanation (this way is not the shortest one.):
the given figure consists of three figures: a semi circle, quarter circle and the rectangle.
375
Step-by-step explanation:
450-75=375
Answer: -11
n+n+1+n+2=-33
n+n+n+1+2=-33
3n=-33-1-2
3n=-36
n=-12
n+1= ==> middle integer
-12+1=-11
A. 40°
∠Z=∠Y (base ∠ of isosΔ)
= 60°
∠X=180-60-60(∠ sum of Δ)
=40°
