Answer:
Step-by-step explanation:
1. r= 5cm
D = 2r = 2(5) = 10cm
C = 2πr = 2π(5)=10π = 31.42 cm
2. r= 11cm
D = 2r = 2(11) = 22cm
C = 2πr = 2π(11)=22π = 69.12 cm
3. r= 15
D = 2r = 2(15) = 30
C = 2πr = 2π(15)=30π = 94.25 cm
4. D = 8 cm
r= D/2 = 8/2 = 4 cm
C = 2πr = 2π(4)=8π = 25.13 cm
5. D = 25cm
r= D/2 = 25/2 = 12.5 cm
C = 2πr = 2π(12.5)=25π = 78.54 cm
