Question

A cloth having an area of $165m^2$ 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 $\frac{5}{7}{m}^2$ on the ground?

Answer 1

Area of rectangle$=lb=165m^2$

Area of circle$=\pi r^2=\pi (5{)}^2=78.5714m^2$

One student occupies$=\frac{5}{7}=0.7143m^2$

$\therefore$ total students $=\frac{78.5714}{0.7143}=110$ students
