Answer:
58.6 cm;
20.1 m
Step-by-step explanation:
✔️Length of arc = θ/360 × 2πr
Where,
θ = 240°
r = 14 cm
π = 3.14
Plug in the values:
Length of arc = 240/360 × 2 × 3.14 × 14
= 58.6133334 = 58.6 cm (nearest tenth)
✔️Length of arc = θ/360 × 2πr
Where,
θ = 105°
r = 11 m
π = 3.14
Plug in the values:
Length of arc = 105/360 × 2 × 3.14 × 11
= 20.1483334 = 20.1 m (nearest tenth)
3.5 because you take 7 and divide by 2 since you have to multiply you base times width to get area I think I might be wrong
