ANSWER:
1) Since the given is in diameter not radius and radius is half of a diameter, therefore, divide the diameter into 2 to get the radius. Answer: 30 cm / 2=15 cm radius A= π r2 A= 3.14 1 15 c x 1 1 cm A= 3.14 * 225 cm2 A=706.5 cm2.
2) 452.16 /3.14 =144
144/2= r
144/2=72 m2
Hope it help
correct me if I'm wrong
