Question

Please answer these few questions on circumference will give BRAINLIEST if correct

Answer 1

Answer:

1) 5.6 x 2 = 11.2

2) 3.8 / 2 = 1.9

3) 6.8 / 2 = 3.4

4) 2.3 x 2 = 4.6

Step-by-step explanation:

Answer 2

In my knowledge

1. C ≈ 35.19mm (r=5.6mm)

C=2πr=2·π·5.6 ≈35.19mm

2. C= 2πr (C= 3.8cm)

r= C/2πr = 3.8/2·π = 0.6cm

r= 0.6cm

3. C= 2πr (C= 6.8m)

r= C/2πr = 6.8/2·π = 1.08m

r= 1.08m

4. C= 14.45m (r= 2.3m)

C=2πr=2·π·2.3≈14.45m

Hope It Helps :)
