Here's the solution ~
The Radius of the circle is 1 ft
now, use the given formula to find the Area of circle ~
[tex]\qquad \sf \dashrightarrow \: \pi {r}^{2} [/tex]
[tex]\qquad \sf \dashrightarrow \:3 ( {1})^{2} [/tex]
[tex]\qquad \sf \dashrightarrow \: 3 (1)[/tex]
[tex]\qquad \sf \dashrightarrow \: 3 \: \: ft {}^{2} [/tex]
The area of given circle is 3 ft²
