-12x-0.4>7.3x+16-55
= -12x-7.3x>16-55+0.4
= -19.3x> -38.6
= x< -38.6/-19.3
= x< 2

Answer:
The radius will change from 0.977 feet to 1.49 feet.
Step-by-step explanation:
The area of a circle with radius r is given by πr².
If the are of the circle is 3 square feet, then πr² = 3, ⇒ r²=
⇒ r² =0.9545, ⇒ r=0.977 feet.
If the area of the circle changes to 7 square feet, then its radius will change to r²=
=2.228, ⇒ r =1.49 feet.
Therefore, the radius will change from 0.977 feet to 1.49 feet. (Answer)
