2 answers:
Answer:
42 square inches.
Step-by-step explanation:
The given expression for the area of the triangular sail is
Here b is the length of the base and h is the height.
Now, we have to find the the area of a triangular sail in a model sailboat when b=12 inches and h=7 inches.
Substituting these values in the above expression to find the area of the triangular sail.
Therefore, the area of triangular sail in a model sailboat when b=12 inches and h=7 inches is 42 square inches.

Answer:
- 150π ft²
- 10π ft.
Step-by-step explanation:
Area of the sector :
Finding the area given r = 30 ft. and θ = 60° :
⇒ Area = π × (30)² × 60/360
⇒ Area = π × 900/6
⇒ Area = 150π ft²
===========================================================
Length of the arc :
Finding the arc length given r = 30 ft. and θ = 60° :
⇒ Arc Length = 2 × π × 30 × 60/360
⇒ Arc Length = 60/6 × π
⇒ Arc Length = 10π ft.
