b)9
c)8
d)9
area of OAB = 72 = (1/2) sin (AOB) * OA * OB solve the above for sin(AOB) to find sin(AOB) = 1/2 area of ODC = 288 = (1/2) sin (DOC) * OD * OD Note that sin(DOC) = sin(AOB) = 1/2, OD = 18 + y and OC = 16 + x and substitute in the above to obtain the first equation in x and y 1152 = (18 + y)(16 + x)...

Answer:
The perimeter is 50.26 inches
Step-by-step explanation:
To find the circumference of the half-circle use d/2
C = 3.14(9 x 2)/2
C = 3.14(18)/2
C = 56.52/2
C = 28.26
P = 5 + 12 + 5 + 28.26
P = 50.26
