Question

Please tell me answer of this question in easy way but Step-by-step
the lower part of a circus tent is cylindrical and the upper part is conical. the radius of the base of the tent is 28m and the height of the cylindrical part is 15 cm. if the slant height of the conical part is 53cm find the canvas required for the tent

Answer 1

Given that, radius(r) = 28cm
length(h)= 15cm
Then, csa of cylinder = 2πrh
=2*22/7*28*15
=44/7*420
=2640 sq.cm
Also Given,slant height(l)= 53cm
Then, CSA of cone=πrl
=22/7*28*53
=22*4*53
=4664 sq.cm
Area of Canvas required for the tent= CSA of cone + CSA of cylinder
=4664+2640
=7304 sq.cm

[First of all, is everthing in meter or centimeter?If everything in meter then also the answer is correct. Or if centimeter then also correct.]
