A figure consists of a square of side z meter with semicircle drawn on the outside of the square. The area (in m2) of the figure so formed will be
সমাধান
সঠিক উত্তর: Option C
Area of the square is z2
And, the radius of the circle drawn on the outside of the square = z/2
Now, the area of the circle is = π(z/2)2 = πz2/4
The are of the semi circle is = 1/2 * πz2/4
= πz2/8
Thus, the area of the entire figure is = z2+πz2/8
