Change in the radius of the circle as the area increases from 3 square feet to 7 square feet

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)
