Question

find the area of the figure formed by the joining semicircle of a diameter 6cm with a triangle of base 6cm and height is 9cm
$\pi = 3.14$
please say frds​

Answer 1

Step-by-step explanation:

Area of figure formed =

Area of Semicircle + Area of Triangle.

Area of semicircle = ( πr^2 ) / 2

= ( 3.14 × 3 × 3 ) / 2 cm^2

= ( 3.14 × 9 ) / 2 cm^2

= ( 28.26 ) / 2 cm^2

= 14.13 cm^2

Area of triangle = (1/2) × base × height

= (1/2) × 6 cm × 9 cm

= (54/2) cm^2

= 27 cm^2

Area if figure formed = (14.13 + 27) cm^2

= 41. 13 cm^2

Area of figure = 41.13 cm^2
