Step-by-step explanation:
step 1. The circumference (c) of a circle is the diameter of a circle x pi. c = d(pi) = 14pi.
step 2. The area (A) of a circle is the radius of a circle squared x pi. The radius of a circle is 1/2 x the diameter. A = (14/2)^2(pi) = 49pi.
y = - 5
substitute the value of x = 4 into the equation and solve for y
- 12 + 9y = - 57 ( add 12 to both sides )
9y = - 45 ( divide both sides by 9 )
y = 
= - 5
