↪SURFACE AREAS AND VOLUMES
↪The VOLUME of any object is nothing but the the capacity to hold the amount of substance inside it . It defines the Amount of substance that can occupied bythe object inside it ..
↪Volume = Base Area × Height
↪thus for the Cylinder ; Volume of cylinder = Pi(R^2) × H
↪thus volume = 3.14 × R^2 × H
↪thus here given as R = 4 cm and H = 12cm
↪Volume = 3.14 × 16 × 12= 602.88 cm^3
thus
↪the Volume of the Cylinder = 602.88 cm^3

71x^2
(71 x squared units of the house will be left).
Subtract Area of house from area of lot.
Area of house - 3x * 2x = 6x^2
Area of lot - 11x*7x= 77x^2
77xx -6xx = 71x^2
you cannot find the x value; not enough information is given.
Here!
<h2>The answer is Option A!</h2>

<h3>Why so??</h3>
Let's see what complex numbers are!

Now we know,

So!


And thus we get the answer!
