Find the approximate area of the sector. Use 3.14 for pi 100 degrees 7 cm
Sector area=___________ cm2
To find the area of a sector, we use the formula:
Sector Area = (θ/360) x π x r^2
where θ is the angle in degrees, π is a constant approximately equal to 3.14, and r is the radius of the sector.
Given that the angle is 100 degrees and the radius is 7 cm, we can substitute these values into the formula:
Sector Area = (100/360) x 3.14 x 7^2
Sector Area = (0.2778) x 3.14 x 49
Sector Area = 0.8736 x 49
Sector Area = 42.7844
Therefore, the approximate area of the sector is 42.78 cm^2.
