Answer: 24.2
Step-by-step explanation:
The answer to this mathematical question would be "0.4x = 4.4". I simply subtracted 1.8x to both sides of the equation (following the subtraction property of equations) and then added 4.4 to both sides of the equation (following the addition property of equations). Thus, we arrive to the answer, 0.4x = 4.4.
Area=rsquared(pi)
24/2=12(12)=144(pi)
Around 452.16
I hope that is correct.
