Radius of the circle with area 32.1square feet is equals to 3.20ft.
What is area?
" Area is defined as the total space occupied by a two dimensional object enclosed in it. It's unit is always square of the given unit of length."
Formula used
Area of the circle 'A' = [tex]\pi r^{2}[/tex]
r = radius of the circle
Value of [tex]\pi = 3.14[/tex]
According to the question,
Given area of the circle,
A = 32.1 square feet
Substitute the value in the formula of area of the circle we get,
32.1 = (3.14) × [tex]r^{2}[/tex]
⇒[tex]r^{2} =\frac{32.1}{3.14}[/tex]
⇒[tex]r^{2} =10.229[/tex]
⇒[tex]r=\sqrt{10.229}[/tex]
⇒[tex]r= 3.198[/tex]
≈3.20 ft
Hence, the radius of the circle is equals to 3.20ft.
