Step-by-step explanation:
Answer:
4in = r
Step-by-step explanation:
Different problem if the x was a variable in the question
formula for area of circle = pi x r^2.
So if the area of a circle is 16 pi in^2, it would be an obvious estimate that the radius is the square root of 16 which is 4 inches.
If the x was a variable, you would find the square root of 16x which is 
which would make it 4
as the radius.

Answer:
<u><em>The error Vikam made:</em></u><u><em> He actually used the wrong expression to represent the area of the base of the given pyramid. </em></u>
Step-by-step explanation:
The surface area of the pyramid that is given = 4 * (0.5 * 34.2 * 28.4) + 34.2 * 34.2
Now, the Total area of it is = (2 * 0.5 * 36.5 * 25.6) + (2 * 0.5 * 37.8 * 16.2) + (25.6 * 16.2)
= (36.5 * 25.6) + (37.8 * 16.2) + (25.6 * 16.2)
