Answer 2

Answer:

Ans1. 10000 square centimetre.

Ans2.Area will be 216 is correct answer.

Ans3.Perimeter of floor=2(l+b)=2(8+5)=2×13=26m

now,lateral surface area as area circumference×height so,

=2(l+b)h

=26×3

=78m^2

Ans4.Total surface area of cone=πr(r+l)

radius (r) base of cone= 16/2=8 m

slant height of cone = 27m

total surface area of cone=πr(r+l)=[(22/7×8×(8+27)]m^2

=[22/7×8×35]m^2

=880m^2 is correct answer
