1.	A conical Tent is 5m High and 24m in Diameter. Find the Cost of Canvas Used in Making the Tent at the Rate of Rs7 Sq m.
Answer» Radius of the tent = 12m Height = 5m Slant height = √(r²+h²) = √(5²+12²) = √(25+144) =√(169) =13m Curved surface area of the tent = πrl =22/7 × 12 × 13 =490.28 =490.3m² Cost of 1m² canvas = ₹7 Cost of 490.3m² canvas = 490.3 ×7= ₹3432.1 hit like if you find it useful

A conical Tent is 5m High and 24m in Diameter. Find the Cost of Canvas Used in Making the Tent at the Rate of Rs7 Sq m.

Answer»

Radius of the tent = 12m

Height = 5m

Slant height = √(r²+h²)

= √(5²+12²)

= √(25+144)

=√(169)

=13m

Curved surface area of the tent = πrl

=22/7 × 12 × 13

=490.28

=490.3m²

Cost of 1m² canvas = ₹7

Cost of 490.3m² canvas = 490.3 ×7= ₹3432.1
