Respuesta :
Find the area of the sector of a circle of radius 5 units subtended by an angle of 3π² radians.
Answer:
370.0 square units
Step-by-step explanation:
The formula for the area of a sector with angle in radians
= 1/2 × r² × θ
In the question
θ = 3π² radians
r= 5 units
Area of a sector = 1/2 × 5² × 3π²
= 370.11016504 square units
Approximately = 370 square units
Answer:
58.9
Step-by-step explanation:
Remember that the area of a sector is given by the formula A=12θr2, where θ is the angle in radians. Because our angle is given in radians, we can just apply the formula to find
A=12θr2=12(3π2)(5)2≈58.9
