The correct question is
Find the area of sector GHJ, given that theta = pi/4 radians. Express your answer in terms of pi and rounded to the nearest tenth (given that GH is a radius of 5 cm)

we know that
[area of a circle]=pi*r²
for r=5 cm
[area of a circle]=pi*5²> 25*pi cm²

if 2*pi radians (full circle) has an area of > 25*pi cm²
 pi/4 radians> x
x=(pi/4)*25*pi/(2*pi)> x=3.125*pi cm²
rounded to the nearest tenth> x=3.1*pi cm²

the answer is
3.1*pi cm²

The correct answer here is c
