  4. Assuming a sector of a circle... find the area of the circle: A = pi r^2, where r = radius find the fraction of the circle that the sector is: example angle of secton/360 degrees or length of sector arc / circumference ( c = 2 pi*r)

  5. ..., you divide the circumference by 3. So, the arc length of each sector is (2/3) * pi * r = (2/3) * (0.5) * pi = pi/3 meters. c . Did you mean area? The area of a circle is pi*r^2. ...

  6. ...arc length. 60 = 15 * theta So, theta = 4 radians. area of sector = theta/(2pi) * pi*r^2 A = 4/(2pi)* pi*15^2 A= 2/pi...pi's cancel A = 450 sq. in. So, the answer is C . 450 sq.in.

  7. First find the area and arc length (which would be circumference) of the whole circle, then find 78/360 of those answers for the sector . C = 2 π r = 12π so arc length = 78/360 • 12π = 13π/5 A = π r² = 36π so area = 78/360 • 36π = 39π/5

  8. Sectors only refer to circles you will need the central angle and the length of the radius (or diameter) of the circle so find the circumference of the circle ( C ) then perimeter = central angle/360 * C hope this helps
