Question

77sq.m tripal is required to make a right circular conical tent. If the slant height of the tent
is 7 m., then let us write by calculating, the base area of the tent.​

Answer 1

Step-by-step explanation:

Diameter =28 m

Radius =

2

28

=14 m (=r)

Height h=3 m

Curved Surface area of Cylinder =2πrh square unit

=2×

7

22

×14×3

=264m

2

Cone:

radius =14 m; h=10.5 m

Slant height l=

h

2

+r

2

=

(10.5)

2

+14

2

=

306.25

=17.5 m

Curved surface area of cone =πrl square unit

=

7

22

×14×17.5

=770m

Total surface area of the tent =264+770=1034m
