Answer:

Explanation:

Question One

Since there are four questions here, I'm going to take some short cuts.

This is a rectangle with 2 equal semicircles. That makes a whole circle.

The diameter of this circle is 16 - 12 = 4

Edit This question was originally incorrect.

So

Circle

Circle = pi*d

Circle = 3.14 * (d)

Circle = 3.14 * 4

Circle = 12.56

Rectangle

Lengths = The perimeter includes 2 lengths.

Lengths = 2 * 12 = 24

Lengths = 24

Total Perimeter

36.56

Answer A

Question Two

Circle

The radius of the circle is 9

The area of the circle is A = pi * r^2

Area of the circle is A = 3.14 * 9^2

Area of the circle is A = 254.34

Square

S (the side = 2*radius

S = 2*9

S = 18

Area of the square = 18^2

Area of the square = 324

Area of the Shaded Part

Area of the shaded Part = 324 - 254.34

Area of the Shaded Part = 69.66

Looks like C is the right Answer

Problem 3

Triangle

b = 8.8

h = 7.8

Area = 1/2 * b * h

Area = 1/2 * 8.8 * 7.8

Area = 34.32

Rectangle holding the triangle up.

Width = 8.8 - 2*3

Width = 8.8 - 6

Width = 2.8

Length = 19.2 - 7.8

Length = 11.4

Area = L * w

Area = 2.8 * 11.4

Area = 31.92

Total Area = 31.92 + 34.32 = 66.24

It looks like some rounding was done. The closest answer is B
