Question

A wheel of diameter 14 cm must rotate ______ times to go 220 cm.​

Answer 1

Step-by-step explanation:

diameter of wheel is 14cm

so radius is d/2= 14/2=7cm

so s

we find circumference

so circumference=2πr

solve - 2×22/7×7=44cm

1 time rotate wheel to complete 44cm

so 220cm complete=220/44= 5 times

ans - 5times rotate wheel
