alleryಚಕ್ರವು 22 km ದೂರವನ್ನು 2500 ಕ್ರಾಂತಿಗಳಲ್ಲಿ ಕ್ರಮಿಸುತ್ತದೆ. ಚಕ್ರದ ವ್ಯಾಸ ಎಷ್ಟು? (π = 22/7 ತೆಗೆದುಕೊಳ್ಳಿ)
A2.8 m
B1.4 m
C5.6 m
D3.5 m
Answer & Solution
Correct answer: A. 2.8 m
1.
ಪ್ರತಿ ಕ್ರಾಂತಿಗೆ ದೂರ = ಒಟ್ಟು ದೂರ / ಕ್ರಾಂತಿಗಳು = 22000 m / 2500 = 8.8 ಮೀ.
2.
ಇದು ಸುತ್ತಳತೆಗೆ ಸಮನಾಗಿರುತ್ತದೆ, ಆದ್ದರಿಂದ πd = 8.8, d = 8.8 × 7/22 ನೀಡುತ್ತದೆ.
3.
d = 61.6/22 = 2.8 ಮೀ.
