1) Radius = 4 ft, Diameter = 8 ft, Area = 16π ft², Circumference = 8π ft
2) Radius = 7 cm, Diameter = 14 cm, Area = 49π cm², Circumference = 14π cm
3) Radius = 9 m, Diameter = 18 m, Area = 81π m², Circumference = 18π m
4) Radius = 13 in, Diameter = 26 in, Area = 169π in², Circumference = 26π in
5) Radius = 16 ft, Diameter = 32 ft, Area = 256π ft², Circumference = 32π ft
6) Radius = 5 in, Diameter = 10 in, Area = 25π in², Circumference = 10π in
7) Radius = 15 m, Diameter = 30 m, Area = 225π m², Circumference = 30π m
8) Radius = 8 m, Diameter = 16 m, Area = 64π m², Circumference = 16π m
9) Radius = 10 ft, Diameter = 20 ft, Area = 100π ft², Circumference = 20π ft
Parent Tip: Review the logic above to help your child master the concept of area and circumference of a circle worksheet.
