Answer:-
2.circumference =2πr
=2×22/7×35
=220cm
3.Diameter =25cm
radius= 25/2cm
It's circumference=2πr
=2×22/7×25/2
= 550/7cm
therefore,
distance covered in 7 revolution=550/7×7
=550 cm
4. diameter = 63cm
radius= 63/2cm
circumference=2πr
=2 ×22/7 ×63/2
=198cm
therefore,
No. of revolutions= 1386/198
=7
