Step-by-step explanation:
height (h) = 10m
height (h) = 10mdiameter (d) = 14 m
height (h) = 10mdiameter (d) = 14 mradius (r) = 14/2 = 7 m
height (h) = 10mdiameter (d) = 14 mradius (r) = 14/2 = 7 mTotal area of the cloth = 300 m²
i. l=√(h²+r²)
l=√[(10)²+(7)²]
l=√[100+49]
l=√149
l=12.2 m
ii. Area of cloth used for the floor
= Total Area of cloth - Area of cloth used in Tent
= Total Area of cloth - CSA of Conical Tent
= 300 - πrl
= 300 - (22/7)×7×12.2
= 300-(22×12.2)
= 300-268.4
= 31.6 m²
iii. Volume of the Tent
= Volume of the cone
= (⅓)πr²h
=(⅓)×(22/7)×(7)²×10
= (⅓)×22×7×10
= (⅓)×1540
= 513.33 m³
iv. Area of the floor of the tent
= Area of the circular base of the conical tent
= πr²
= (22/7)×7×7
= 154 cm²

This is guarantee correct
by pran mkrheight (h) = 10m
diameter (d) = 14 m
radius (r) = 14/2 = 7 m
Total area of the cloth = 300 m²
i. l=√(h²+r²)
l=√[(10)²+(7)²]
l=√[100+49]
l=√149
l=12.2 m
Hence, b) would be the correct option.
ii. Area of cloth used for the floor
= Total Area of cloth - Area of cloth used in Tent
= Total Area of cloth - CSA of Conical Tent
= 300 - πrl
= 300 - (22/7)×7×12.2
= 300-(22×12.2)
= 300-268.4
= 31.6 m²
Hence, a) would be the correct option.
iii. Volume of the Tent
= Volume of the cone
= (⅓)πr²h
=(⅓)×(22/7)×(7)²×10
= (⅓)×22×7×10
= (⅓)×1540
= 513.33 m³
Hence, c) would be the correct option.
iv. Area of the floor of the tent
= Area of the circular base of the conical tent
= πr²
= (22/7)×7×7
= 154 cm²
