alleryਇੱਕ ਪਹੀਆ 2500 ਘੁੰਮਣ ਵਿੱਚ 22 km ਦੀ ਦੂਰੀ ਤੈਅ ਕਰਦਾ ਹੈ। ਪਹੀਏ ਦਾ ਵਿਆਸ ਕੀ ਹੈ? (π = 22/7 ਲਓ)
A2.8 m
B1.4 m
C5.6 m
D3.5 m
Answer & Solution
Correct answer: A. 2.8 m
1।
ਦੂਰੀ ਪ੍ਰਤੀ ਕ੍ਰਾਂਤੀ = ਕੁੱਲ ਦੂਰੀ / ਕ੍ਰਾਂਤੀ = 22000 m / 2500 = 8.8 ਮੀਟਰ।
2।
ਇਹ ਘੇਰੇ ਦੇ ਬਰਾਬਰ ਹੈ, ਇਸਲਈ πd = 8.8, d = 8.8 × 7/22 ਦੇਣਾ।
3।
d = 61.6/22 = 2.8 ਮੀ.
