Question

A circus tent has a base radius of 50 m. The ring at the centre for the performance by an artists is 20 m in radius. Find the area left for the audience. (Take r = 3.14)

Answer 1

Solution:-

Area of the circle = πr²
Area left for the audience = Area of the whole circus tent - Area left for the performance 
⇒ (3.14*50*50) - (3.14*20*20)
⇒ 7850 - 1256
⇒ 6594 m²
So, the area left for the audience is 6594 square meter.
