1. ### 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 (...

5. ### 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

10. ### A sector angle of a circle with a radius 9cm measures 5pi/12. What is the perimeter of the sector ?

well the straight sides add up to 18 and the curved side will be: (2pi9)(5/24) 18pi(5/24) 3pi(5/4) 15pi/4 final answer 18 + 15pi/4 the 5/24 above came from 5pi/12 divided by 2pi, why because you need to know what fraction of a full circle the given angle is. so given measure...
