Answer:
Perimeter = 18 + 9pi
Area = 81 - 20.25*pi
Step-by-step explanation:
Perimeter = 9 + 9 + 2(2 pi r)/2 The twos cancel out.
Perimeter = 18 + 9*pi
Area of the square = 9 * 9 = 81 cm^2
Area of the 2 semicircles = 2 * pi * r^2/2
r = d/2
d = 9
r = 9/2 = 4.5
Area of the 2 semicircles = 2 (pi * 4.5^2)/2
Area of the 2 semicircles = 20.25 pi
Area of the blue figure = 81 - 20.25 pi
Positive
Positive for ascend change, negative for otherwise
R u in 6th grade cause i can't answer this question
A, I had to look for a second
ACD and CEB are equal and CDE is not equal to either of them
so the right answer is A
the perimeter of is 32 cm
of the perimeter is 32 and the base is 12. then the other two sides are both 10 cm.
