Find the circumference of a circle that has a diameter of 70 cm.
2 answers:
Circumference of circle = 2πr
- π = 3.14
- r = diameter/2 ; 70/2 = 35
Hence , r is 35 cm
- r denotes radius of circle
⇛Circumference of circle = 2πr
⇛Circumference of circle = 2*3.14*35
⇛Circumference of circle = 6.28*35
⇛Circumference of circle = 219.8 cm
Hence , Circumference of circle is 219.8 cm
Answer:
70 pi cm
219.80 cm
219.9114858 cm
Step-by-step explanation:
The circumference of a circle is given by
C = pi*d
C = pi * 70cm
Using 3.14 for pi
C = 219.80cm
Using the pi button
219.9114858cm
