Answer:
The area of sector is 7.48 unit²
Step-by-step explanation:
Given as :
The radius of circle = r = 3 unit
The measure of central angle =Ф = radian
Let The area of sector = A unit²
<u>Now, According to question</u>
Area of sector = π× radius × radius ×
Or, A = π× r × r ×
Or, A = π× r × r ×
where π = 3.14
∵ 180° = π radian
So, 360° = = 2 π radian
Or,, A = π× r × r ×
Or, A = π× r × r ×
Or, A = 3.14 × 3 unit × 3 unit ×
Or, A = 3.14 × 3 unit × 3 unit × 0.2647
∴ A = 7.48 unit²
So,The area of sector = A = 7.48 unit²
Hence, The area of sector is 7.48 unit² Answer
