➷ Use this formula:
Area of circle = 
However, as we are using 3.14 for 'pi', we can write it like this:
Area = 
'r' is the radius which is 12ft
Substitute this value into the equation:
Area = 
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

The longest of the four side lengths is 24 cm
<h3>How to find the value of the longest of the four side lengths?</h3>
The given parameters are:
Perimeter, P = 90 cm
The lengths are consecutive integers
Let the smallest be
Smallest = x
So, we have
P = x + x + 1 + x + 2 + x + 3
Evaluate the like terms
P = 4x + 6
Substitute P = 90 cm in P = 4x + 6
4x + 6 = 90
Subtract 6 from both sides
4x = 84
Divide by 4
x = 21
The longest side is
Longest = x + 3
This gives
Longest = 21 + 3
Evaluate
Longest = 24
Hence, the longest of the four side lengths is 24 cm
