Elan Coil [88]

Answer:

13. 9.77 inches (rounded to 3 s.f.)

14. 249m² (rounded to 3 s.f.)

Step-by-step explanation:

13. To find the arc length, the formula is the angle of the arc out of 360° multiplied by the circumference of the full circle. Circumference of circle: pi × r × 2

\frac{80}{360} × pi × 7 × 2 = 3\frac{1}{9}pi

                       = 9.77 inches (rounded to 3 s.f.)

14. To find the sector area, the formula is the angle of the sector out of 360° multiplied by the area of the full circle. Area of circle: pi × r × r

\frac{285}{360} × pi × 10 × 10 = 79\frac{1}{6}pi

                          = 249m² (rounded to 3 s.f.)
