Answer: Radius is 15.9975 meters.
Step-by-step explanation:
The formula to find radius of circle is r= so plug in our known variables and solve...
r=
r=
r=15.9975
Start by combing like terms. You will get 3x+12=51. Now subtract 12 from both sides (3x=39). Divide both sides by 3 (x=13). The answer is 13.

Answer:
39.0953=39cm2
Step-by-step explanation:
Minor arc =70
Angle of arc=70
Then this sector =70/360=7/36 of the circle
Then area = 7/36x3.14x8x8=39cm2 approximatly
