Find the area of the sector of a circle with radius 3m, if the angle of the sector is 60o
Answer Details
To find the area of a sector, we use the formula:
Area of sector = (θ/360) x πr²
Where θ is the angle of the sector in degrees, r is the radius of the circle, and π (pi) is a mathematical constant approximately equal to 3.14.
In this problem, the radius is given as 3m and the angle of the sector is 60°. Substituting these values into the formula, we get:
Area of sector = (60/360) x π(3)²
= (1/6) x π(9)
= (1/6) x 28.27
= 4.71m² (rounded to two decimal places)
Therefore, the area of the sector of the circle with radius 3m and angle 60° is approximately 4.71m². The answer is option C.
