Knowing the answer options, I've attempted to work out the dimensions, because the resolution of the screenshot is rather low to read with certainty.
(1) Height=radius=8m. Surface area including circular base and top=2πrh+2πr2=128π+128π=256π=804.25m2 (answer B).
(2) The dimensions are 10km, 7km, 3km, surface area=2(10×7+10×3+7×3)=2(121)=242km2 (answer B).
(3) Pentagon side=height=8mi. Area of side=64mi2, 5 sides' area=5×64=320mi2.
Pentagon base and top can each be divided into 5 isosceles triangles of height=5.5mi and base=8mi.
Area of one triangle=4×5.5=22mi2, area of 10 triangles=220mi2, so total area=320+220=540mi2 (answer B).
(4) Rectangular sides 9 by 10=90mi2 each, so total side area=3×90=270mi2.
Area of triangular base=4½×10=45mi2 each. Triangular area total=90mi2, so total area=270+90=360mi2 (answer C).
(5) Volume=πr2h=π×49×6=923.63mi2 (answer B).
(6) Triangular prism. Volume=base area times height.
The dimensions of the triangular base used are base=12ft, two sides are 4ft and 9ft. These give a height of 2.27ft and a base area of 6×2.27=13.62. The height of the prism=4ft so volume=4×13.62=54.48ft3 (answer D).
