1. ### Radians help( Sector area)?

Dude...it's spelled pi, not pie. Since pi/2 is the same as 90 degrees, they are looking for 1/4 of the area of the full circle: area of sector = (1/4)225pi = (225/4)pi = 56.25pi = 176.7145868 square inches

4. ### what is the area of a sector of a circle that has a diameter of 10in. If the length of the arc is 10in.?

Let the sector angle be θ radius = 5 in. Length of arc = 10 in 2πrθ/360° = 10 10πθ = 3600 ° πθ = 360° θ = (360/π)° -------- (1) Area of sector = πr^2θ/360° = 25πθ/360° = 25*360/360 (...

9. ### Finding the radii given the sector of a circle's perimeter and area?

2r+r*theta = 7 => theta = (7-2r)/r (1/2)r^2 * theta = 3 => (1/2)r (7-2r) = 3 => 2r^2-7r+6 = (2r-3)(r-2) = 0 r = 1.5 cm, 2 cm

10. ### What is the area of this circular sector ? GRADE 8?

15 degrees is 15/360 of a whole circle 15/360 = 1/24 so if the whole circle has 144*pi cm^2 then 15 degree is 1/24 * 144pi = 6*pi cm^2
