so for question 2 find the area of the rectangle first:
then you find the area of the triangles:
Add up all the answers:
and for question 3, part A, you just find the area of the 2 boxes and multiply:
so the surface area of the box is 90 square inches therefore the paint covered 90 square inches. For part B, just add up the length of the thick black lines:

Answer:
P371,639.507
Step-by-step explanation:
First year: 70,000
Second year: 72,100
Third year: 74,263
Fourth year: 76,490.89
Fifth year: 78,785.6167
If you plus them all the total is 371,639.507
Answer:
12
Step-by-step explanation:
26+(-2)=26-2=24
24÷2=12
14. the length of the arc is found by using the formula 2*PI*r*angle/360
the circle has a radius of 2 and the known angle is 90 degrees
so you now have: 2 * pi * 2 * 90/360, since the answer needs to be in terms of PI, remove pi from the equation for now:
2*2 *90/*360 = 1
the arc length = 1PI, or just PI
16. the area of the parallelogram is L x W : 9 *6 = 54
the area of the circle is: PI *r^2 = pi * 3^2 = 28.26
area of shaded region is subtracting the area of the circle from the parallelogram: 54 - 28.26 = 25.74 square inches
