शंकूच्या आकाराच्या तंबूच्या पायाची त्रिज्या 9 मीटर आहे आणि त्याची उंची 12 मीटर आहे
वापरलेली संकल्पना:
शंकूचे वक्र पृष्ठभागाचे क्षेत्रफळ = π × त्रिज्या × तिरकी उंची
तिरकस उंची =
गणना:
शंकूच्या आकाराच्या तंबूची तिरकी उंची =
म्हणून, शंकूच्या आकाराचे तंबूचे वक्र पृष्ठभागाचे क्षेत्रफळ = π × 9 × 15 = 135π चौमी
अशा प्रकारे, सामग्रीची किंमत = (135π × 100) ÷ π = 13,500 रु.
∴ सामग्रीची किंमत 13,500 रु.असेल.
