Answer:
13.76
Step-by-step explanation:
Area of the whole
The area of the whole = s^2 (the firgure is a square
s = 8
Area of the whole = 8^2 = 64
Area of the unshaded part
The 2 half circles = 1 whole circle
The radius of the 1/2 circle = 4 (eight has been cut in half)
Area of two half circles = 2* (pi r^2/2)
Area of two half circles = 2 * (pi 4^2/2)
area of two half circles = 16*pi
Area of the shaded area
Area of the shaded area = area of the whole - area of the unshaded area
Area of the shaded area = 64 - 16*pi
Area of the shaded area = 64 - 3.14*16 = 13.76
128/100=32/25
..................
Since t=3
What do have to do is just set it for 3.
13(3) -2
k(3) = 37
Check the picture below
so hmmm, all you really have is 4 triangles and 1 rectangle, notice the bases and altitude of each triangle
so, get the area of each, sum them up, and that's the area of the shape
