Ans.
A) 14m
B) 12m
C) 16m
D) 88m
Read Solution (Total 2)
-
- A) 14 m
1000 rev ---> 88000 m
1 rev ---> 88 m
Perimeter = 2πr = 88 m
2*(22/7)*r = 88
r = 14 m. - 4 years agoHelpfull: Yes(3) No(1)
- for thousand revolution it covers 88 km
for one revolution it cover 88000/1000 = 88m
circumference of circle =2 x pie x radius
2 x pie x radius = 88
radius = 14
diameter = 2x 14 = 28m. - 4 years agoHelpfull: Yes(0) No(0)
