Question

a circus tent is cylindrical to a height of 3m and conical above it. if its diameter is 105m and slant height of cone is 5m. calculate the area of total canvas required.

Answer 1

In this question,
Diameter of Cylinder = 105 m
Radius of Cylinder = 105/2 m = 52.5 m
Height of Cylinder = 3 m

C.S.A of Cylinder = 2 x pi x r x h
=> C.S.A = (2 x 22/7 x 52.5 x 3) m^2
=> C.S.A = 6930/7 m^2
=> C.S.A = 990 m^2

Now,
Radius of Cylinder = Radius of Cone = 52.5 m
Slant Height = 5 m

C.S.A of Cone = pi x r x l
=> C.S.A = 22/7 x 52.5 x 5
=> C.S.A = 5775/7 m^2
=> C.S.A = 825 m^2

Now,
Total Area of Canvas = C.S.A of Cylinder + C.S.A of Cone
=> Total Area = (990+825) m^2
=> Total Area = 1815 m^2

Answer 2

Answer:

Step-by-step explanation:

Diameter of Cylinder = 105 m

Radius of Cylinder = 105/2 m = 52.5 m

Height of Cylinder = 3 m

C.S.A of Cylinder = 2 x pi x r x h

=> C.S.A = (2 x 22/7 x 52.5 x 3) m^2

=> C.S.A = 6930/7 m^2

=> C.S.A = 990 m^2

Now,

Radius of Cylinder = Radius of Cone = 52.5 m

Slant Height = 5 m

C.S.A of Cone = pi x r x l

=> C.S.A = 22/7 x 52.5 x 5

=> C.S.A = 5775/7 m^2

=> C.S.A = 825 m^2

Now,

Total Area of Canvas = C.S.A of Cylinder + C.S.A of Cone

=> Total Area = (990+825) m^2

=> Total Area = 1815 m^2
