Question

tent is in the shape of a cylinder surmounted by a conical top if the height and diameter of the cylindrical Pata 2.1 M and 4 m respectively and the slant height of the tower is 2.8 M find the area of the Canvas used for making the 10 find the cost of Canvas of the tent @ rupees 500 m square also find the volume of a are enclosed in the tent

Answer 1

Answer:

Step-by-step explanation:

height(h)=2.1 m

Radius(r)=2 m

slant height(l)=2.8 m

now,

Csa= pi*r*l=(22/7)*2*2.8=17.6 m square

Cost of Canvas= 500*17.6= Rupees 8,800

Volume (V)= 1/3*area of base*height=1/3pi*r^2*h=(1/3)*(22/7)*(2^2)*2.1

                                                                               = 8.8 m cube

Answer 2

the total area of the tent =Area of the cone +area of the cylinder = 2πrh + πrl

=πr( 2h + l )

=22/7 ×2 ( 2×21/10 +28/10 )

= 44/7 (42/10 + 28/10)

= 4.4 m²

Cost = 4.4 ×500

= 2200
