I find it easier to have a visual for when solving for shapes. You should solve for area of the semicircles by doing A=(3.14r^2)/2
Radius in this case is the base /2
In a Calculator that can be inputted as (3.14(4))/2
for this problem though I'm afraid that I need to know whether the height belongs to the figure as a whole or just regarding the rectangle.
If it is just the rectangle then we can do A=B*h
A= 4*5= 20
20 + semicircle
20 + 6.28
Total= 26.28
2/5 is the answer unless your multiplying
Answer: C. the graph contains (1, 1/10)
Step-by-step explanation:
When x=1, 
.
X=4.5 or 4 and 1/2 because 4 multiplied by -4.5 equals -18 then add 12 now you got -6
5*2 = 10
3^2 = 3*3 = 9
10 + 9 = 19
Answer: 19
