Ответ:
A. 442.05
Step-by-step explanation:
✔️First find the radius of circle J:
θ = 43°
Acr length = 52.8
Thus,
Acr length = θ/360*2πr
Plug in the values
52.8 = 43/360*2*π*r
52.8 = 0.751r
Divide both sides by 0.75
52.8/0.75 = r
r = 70.4 (nearest hundredth)
✔️Find the Circumference of circle J:
Circumference = 2πr
Radius (r) of circle J = 70.4
Plug in the values
Circumference = 2*π*70.4
= 442.34
This is close to the answer in option A. Therefore, the answer is 442.05.
