Question

Find the area of shaded portion

Answer 1

Answer:

Here, we have to subtract the area of the circle from the area of the square

Area of square = a²

= 25 x 25

= 625cm²

Area of circle = πr²

= 3.14 x 10 x 10

= 314 cm²

Area of shaded portion = 625 - 314

= 311 cm²

Answer 2

Answer:

area of a square-area of a circle= area of a shaded region

25×25-22/7×10×10

as area of square is S×S

and area of circle is pie r²

so solving above equation we get

625-314.29

310.71.
