Step-by-step explanation:
here's the solution :-
1st question :
the given figure has a triangle and a semi - circle, so area
in the triangle,
base = 3 cm
height = 4 cm
so, area of triangle
=γ
=γ
about the semi - circle, radius = 4 / 2 = 2 cm
so, area =
=γ
=γ
area of circle = 6.28 sq.cm
=γ area of triangle + area of semi - circle
=γ6 + 6.28 = 12.28 sq.cm
2nd question :-
the given figure is a rectangle with a semi - circle
so, about the rectangle
length = 12 inwidth = 6 inarea =
=γ
=γ
about the semi - circle,
radius = 6 / 2 = 3 in
area =
=γ
=γ
area of the figure =
=γarea of rectangle + area of semi- circle
=γ72 + 14.13
=γ86.13 sq.in
line is slope
