Please help me out i need this turned in now

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

=》

=》

about the semi - circle, radius = 4 / 2 = 2 cm

so, area =

=》

=》

area of circle = 6.28 sq.cm

=》 area of triangle + area of semi - circle

=》6 + 6.28 = 12.28 sq.cm

2nd question :-

the given figure is a rectangle with a semi - circle

so, about the rectangle

area =

=》

=》

about the semi - circle,

radius = 6 / 2 = 3 in

area =

=》

=》

area of the figure =

=》area of rectangle + area of semi- circle

=》72 + 14.13

=》86.13 sq.in
