Answer:
Area = pi r²
area = 22/7 × 12 × 12 = 452.57 in²
given,
height of triangle(h)=3.5 in.
base of triangle (b)=4 in.
length of side of triangle(s)= 4 in.
length of prism(l)=9 in.
we have,
surface area of traingular prism( A)=bh+2ls+lb
=4×3.5+2×9×4+9×4
=14+72+36
=122 square inches
I hope this helps you
circle area=pi.5^2=25pi=78,5
polygons area=5×5×7,3/2=182,5
Shaded area=182,5-78,5=104
