4. analyze the diagram below and complete the instructions that follow. plss

Option D. DE/DF

Step-by-step explanation:

The following data were obtained from the question:

Opposite = DE

Hypothenus = DF

Adjacent = EF

Sin θ =.?

From trigonometrical operations,

Sin θ = Opposite/Hypothenus.

With the above information, we can find Sin θ as follow:

Sin θ = Opposite/Hypothenus.

Sin θ = DE/DF.

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units

step-by-step explanation:
