Can anyone answer this question

Answer 1

Answer:

(i) 229.86 cm2

(i) 235.4 cm3

Step-by-step explanation:

(i)TSa of the figure => TSA of sq. + Csa of Hemisphere - $\pi$ r2

6a^2 + $\pi$ r2

6(6)^2 + $\pi$ * (2.1)^2

216+13.86 => 229.86

(ii) Volume of the figure is => vol. of the sq. + vol. of hemisphere

a3 +2/3$\pi$ r^3

216+19.4

=> 235.4
