Given :- The stage is in the shape of a semi-circle and a rectangle, as shown below. All area is to painted. 1 liter of paint is needed to paint 5m? How many liters of paint is needed ?

Answer :-

→ Total area = Area of semi - circle + Area of rectangle = (π *3²)/2 + 10 * 4 = 4.5π + 40 = 14.13 + 40 = 54.13 m² .

so,

→ for 5m² paint needed = 1 litre

→ for 1m² paint needed = (1/5) litre

then,

→ for 54.13 m² paint needed = (1/5) * 54.13 10.8 litre .
