Answer:
((w+4)/3)+b)/2
Step-by-step explanation:
w = 3(2a-b)-4
w+4 = 3(2a-b)
(w+4)/3 = 2a - b
((w+4)/3)+b = 2a
a = ((w+4)/3)+b)/2

Answer:
2.43 (units)
Step-by-step explanation:
Circumference of a circle is defined by C=2pi*r
Solving that equation for r --> 5.5 = 2* 3.14 * r
r=0.88 unit
Area of a circle = A= pi * r^2
Solve this equation by plugging in the r we just found. A = 3.14 * (0.88^2)
Answer: 2.43 units
