Question 21 Volume And Surface Area Of Solids Exercise 15C

A cloth having an area of 165 m2 is shaped into the form of a conical tent of radius 5m.

How many students can sit in the tent if a student, on an average, occupies 5/7 m2 on the ground?

A cone is a solid three-dimensional geometric object with a circular base and a pointed apex at the top. A cone is made up of one face and one vertex. For a cone, there are no edges.

We know that

Area of the floor of the tent = πr2

By substituting the values

Area of the floor of the tent = (22/7) × 52 = 550/7 m2

We know that the area required by one student is 5/7 m2

So the required number of students = (550/7)/ (5/7) = 110 Related Questions
