Answer:

The area of the resulting cross section is
$78.5\ m^(2)$

Explanation:

we know that

The resulting cross section is a circle congruent with the circle of the base of cylinder

therefore

The area is equal to

$A=\pi r^(2)$

we have

$\pi=3.14$

$r=10/2=5\ m$ -----> the radius is half the diameter

substitute the values

$A=(3.14)(5)^(2)=78.5\ m^(2)$
