Step-by-step explanation:
Given radius =10.5 cm
We know that, Circumference of the circle is C=2πr
=(2×22/7×10.5)
=(21×22/7)
=66 cm
Thus, the circumference of the circle is 66 cm

Answer:
i) 15.4 cm,ii) 28.6 cm,iii) 26.4 cm,iv) 44 cm
Step-by-step explanation:
i) 10.5 cm
2πr=2*22/7*10.5
=44*3.5
=15.4 cm
ii) 4.55 cm
2πr=2*22/7*4.55
=44*0.65
=28.6 cm
iiI) 4.2 cm
2πr=2*22/7*4.2
=44*0.6
=26.4 cm
iv) 7cm
2πr=2*22/7*7
=44*1
=44 cm
good try but the first question's Answer is wrong. So it's a request that no one should write it ☺️. Otherwise good attempt you have made
