➷ Use this formula:

Area of circle = $\pi r^{2}$

However, as we are using 3.14 for 'pi', we can write it like this:

Area = $(3.14)r^{2}$

'r' is the radius which is 12ft

Substitute this value into the equation:

Area = $(3.14)12^{2}$

Solve:

Area = 452.16

Multiply this value by 0.75 to get the answer:

452.16 x 0.75 = 339.12

339.12 square feet is being watered
