Detailed Solution
Download Solution PDFदिलेल्याप्रमाणे:
r = 7 सेमी
एकूण पृष्ठफळ = 1144 सेमी²
वापरलेले सूत्र:
वृत्तचितीचे एकूण पृष्ठफळ= 2πr(h + r)
गणना:
ही मूल्ये सूत्रामध्ये बदलून
⇒ 1144 = 2 × (22/7) × 7 × (h + 7)
समीकरण सरलीकृत करा:
⇒ 1144 = 44 × (h + 7)
दोन्ही बाजूंना 44 ने विभाजित करा
⇒ 1144 / 44 = h + 7
⇒ 26 = h + 7
शेवटी, h साठी सोडवा:
⇒ h = 26 - 7 = 19 सेमी
म्हणून, वृत्तचितीची उंची 19 सेमी आहे.
