Download Solution PDF6 सेमी व्यासाचे काही शिशाचे गोळे एका वृत्तचितीकार बीकरमध्ये टाकले जातात ज्यामध्ये थोडेसे पाणी असते जेणेकरून ते पूर्णपणे बुडलेले असतात. बीकरचा व्यास 9 सेमी असल्यास आणि पाण्याची पातळी 32 सेमीने वाढली असल्यास, बीकरमध्ये टाकलेल्या शिश्याच्या गोळ्यांची संख्या शोधा.
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFदिलेल्याप्रमाणे:
गोळ्याची त्रिज्या 3 सेमी आहे
वृत्तचितीची त्रिज्या आणि उंची 4.5 सेमी आणि 32 सेमी आहे
वापरलेले सूत्र:
गोळ्याचे घनफळ = 4/3πr³
वृत्तचितीचे घनफळ = πr²h
गणना:
घातलेल्या गोळ्याचे घनफळ = पाण्याचे वाढलेले प्रमाण
गोळ्याची त्रिज्या = 6/2 = 3 सेमी
वृत्तचितीची त्रिज्या = 9/2 = 4.5
म्हणून,
(4/3)π × (3)³ × गोळ्यांची संख्या = π (4.5) × (4.5) × 32
⇒ गोळ्यांची संख्या = 18
∴ योग्य उत्तर पर्याय 2 आहे.
