Answer:
Circumference formula:
- C = πd
π is the constant and π = 3.14
- A) C = 3.14*3 cm = 9.42 cm
- B) C = 3.14*10 = 31.40 cm
- C) d = 24/3.14 = 7.64 cm
- D) d = 18/3.14 = 5.73 cm
- E.) C = 3.14*1 = 3.14 cm
Answer:
Círclє Díαmєtєr Círcumfєrєncє
( A ). 3 cm 9.42 cm
( B ). 10 cm 31.40 cm
( C ). 7.64 cm 24 cm
( D ). 5.73 cm 18 cm
( E ). 1 cm 3.14 cm.
Step-by-step explanation:
Formula used
◈ Circumference of circle = π × diameter
◈ Diameter of circle = Circumference of circle / π
Solution
usíng vαluє σf π = 3.14
( A ) Díαmєtєr = 3 cm
Círcumfєrєncє = 3.14 × 3 = 9.42 cm.
( B ) Díαmєtєr = 10 cm
Círcumfєrєncє = 3.14 × 10 cm = 31.40 cm.
( C ) Círcumfєrєncє = 24 cm
Díαmєtєr = 24 / 3.14 cm = 7.64 cm.
( D ) Círcumfєrєncє = 18 cm
Díαmєtєr = 18 /3.14 = 5.73 cm.
( E ) Díαmєtєr = 1 cm
Círcumfєrєncє = 3.14 × 1 cm = 3.14 cm.
