Solution:
Note that:
- Area of circle: πr²
- r = 11 ft.
Substitute the radius in the expression to find the area of the circle.
- (π)(r²)
- => (22/7)(11²)
- => (22/7)(121)
- => 380.29 ft² (Rounded)
The formula to find area of circle is:
[tex] \boxed{ \mathfrak \red{ area = \pi r ^{2} }}[/tex]
Where,
- r is radius
- the value of pi is constant
In our case,
- r = 11 ft
- pi = 3.14

[tex] \green{ \sf \: area = 3.14 \times 121}[/tex]
[tex] \blue{ \sf \: area = 379.94 \: {ft}^{2} }[/tex]
