Answer:
6.) 43.96 cm
7.) 28.26 inches
8.) 75.36 mm
9.) 47.1 cm
10.) 21.98 m
Step-by-step explanation:
Formula for circumference of a circle: πd or π2r
let π = 3.14
6. r=7
= π2r
= π (2) (7)
= 43.96 cm
7. d=9
=π (9)
= (3.14) (9)
= 28.26 in
8. (3.14) (12) (2)
=75.36 mm
9.) (3.14) (15)
=47.1 cm
10.) (3.14) (2) (3.5)
= 21.98 m
