Answer:
AC and DF
Step-by-step explanation:
Corresponding sides as well as corresponding angles have a pair of same angles or sides that are in the same place in two different shapes that are similar.
Find attached the diagram used for solving the question
Since Δ ABC = Δ DEF
∠B corresponds to ∠E
∠A corresponds to ∠D
∠C corresponds to ∠F
As a result of the above:
Line AB corresponds to line DE
Line AC corresponds to line DF
Line BC corresponds to line EF
Therefore, if Δ ABC = Δ DEF, one of the pair of corresponding parts would be AC and DF.
Given:
radius of cone = r
height of cone = h
radius of cylinder = r
height of cylinder = h
slant height of cone = l
Solution
The lateral area (A) of a cone can be found using the formula:
where r is the radius and l is the slant height
The lateral area (A) of a cylinder can be found using the formula:
The ratio of the lateral area of the cone to the lateral area of the cylinder is:
Canceling out, we have:
Hence the Answer is option B
