Question

Find the area of a circle with a radius of 11ft. Use 3.14 or 22/7 for pie.

Answer 1

The formula to find area of circle is:

`\boxed{ \mathfrak \red{ area = \pi r ^(2) }}`

Where,

• r is radius
• the value of pi is constant

In our case,

• r = 11 ft
• pi = 3.14

`\orange { \sf \: area = 3.14 * {11}^(2) }`

`\green{ \sf \: area = 3.14 * 121}`

`\blue{ \sf \: area = 379.94 \: {ft}^(2) }`

Answer 2

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)
