The complete question in the attached figure
we know that
the equation of a sphere is
(x-h)²+(y-k)²+(z-l)²=r²
<span>let's assume that the center of the sphere is at the origin
</span>so
(h,k,l)-------> (0,0,0)
for r=16 m
(x-h)²+(y-k)²+(z-l)²=r²--------> (x)²+(y)²+(z)²=16²
for z=9 m
(x)²+(y)²+(9)²=16²--------> (x)²+(y)²=256-81--------> (x)²+(y)²=175
the radius of the circle is r=√175 m
so the area of the circle A=pi*r²-----> A=pi*175-----> A=549.5 m²
the answer is the area of the circle is 549.5 m²
9/10 is equivalent to 90/100 and the answer under mine or above or the other answer should be reported. They got points for a question they did not answer correctly.

Answer: Choice D) Angle Angle Side (AAS)</h3>
Explanation:
The marked angles in red are a congruent pair of angles. This forms the first "A" in "AAS".
The vertical angles are another pair of congruent angles. This is the other "A" in "AAS".
The tickmarks indicate those segments are the same length, so that forms the "S" in "AAS".
The sides are not between the angles mentioned for any given triangle, so we use AAS instead of ASA.
