A pyramid having circular base is called cone. (बृतकार आधार भएको पिरामिडलाई सोली भनिन्छ ।)
(i) To find the curved surface area of cone. (सोलीको बक्र सतहको क्षेत्रफल निकाल्न ।)[br](ii) To find the total surface area of cone. (सोलीको पुरा सतहको क्षेत्रफल निकाल्न ।)[br](iii) To find the volume of cone. (सोलीको आयतन निकाल्न ।)

1. If radius (r) = 3 cm and height (h) = 7 cm then which of the following is the volume of cone? (यदि अर्धब्यास (r)= 3 cm र उचाइ (h) = 7 cm भए सोलीको आयतन कति हुन्छ ?)
2. If radius (r) = 3 cm and slant height (l) = 7 cm then which of the following is the curved surface area of cone? (यदि अर्धब्यास (r)= 3 र छडके उचाइ (l) = 7 भए सोलीको बक्र सतहको क्षेत्रफल कति हुन्छ ?)
