EEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEExrfk

Answer 1

• 38.4895 cm^2
• 190.091 cm^2

Solution,

radius =7 cm

Area of quarter circle=pi r^2/4

= 3.142*(7)^2/4

=3.142*49/4

=38.4895 cm^2

Solution,

radius=11 cm

Area of semicircle= 1/2 pi r^2

=1/2*pi*(11)^2

= 1/2*3.142*121

=190.091 cm^2

hope it helps

Good luck on your assignment
