Question

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

Answer 1

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)

Answer 2

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

$\orange { \sf \: area = 3.14 \times {11}^{2} }$

$\green{ \sf \: area = 3.14 \times 121}$

$\blue{ \sf \: area = 379.94 \: {ft}^{2} }$
