Explanation:
a) The more like a cube or a ball the figure is, the smaller its surface area.
b) Solids with smaller surface area have nearly the same dimension in every direction.
c) Solids with larger surface area have a very high ratio between the largest dimension and the smallest dimension. The flatter or more string-like the figure is, the larger its area.
ok if GH line length is that 8.6 you do the following:
since OH and OG are radiuses they are equal, we have in the triangle two equal angles beside 82 means each angle is 49 degree, now use "sine law" sine 82 / GH (8.6) = sine 49 / OH, OH equal 6.55, this is the radius, theta = arc/radius, provided that theta is in radian, 82 degree in radians would be 1.43 something multiply that by 6.55 (radius) you get arc GH = 9.4, since GH and HJ arcs are congruent hj = 9.4, if the answer is wrong tell me to revise in case you have a guide answre
i think c might be the right answer
Answer:
verdical lines have an undefined slope so it might be 4
