Answer:
388
Step-by-step explanation:
We need to find the area of the semicircle and parallelogram separately and then combine.
The formula for the area of a semicircle is 1/2(pi*r^2)
r = 12. 12^2 = 144
1/2(pi*144) = 226..1946711 which we can just round to 226
The formula for the area of a parallelogram is bh
b = 18, h = 9. 18*9 = 162.
226+162 = 388
Answer:
138
Step-by-step explanation:
perimeter of rectangle=2(l+b)
=2(53+16)
=2(69)
=138
Going to add on to your variables for the sake of the formula.
Let A = the amount after T years.
P = Principal amount




or ≈ $562.43
