nikklg [1K]

Answer:

Large baking dish of cylinder, cone and sphere.

Step-by-step explanation:

When we compute the volume of each of the small and large baking dish taking $\pi$ =3.14, we get

Volume of cylinder (small dish)= $\pi$ (r^2)(h)

=3.14( $\frac{3}{2}$ )^2*3

= $\frac{3.14*9*3}{4}$

= 21.195

Volume of cylinder (large dish)= $\pi$ (r)^2(h)= 3.14*(3)^2(3)

=84.78

Similarly, volume of cone (smaller dish)= $\frac{1}{3} \pi r^{2} h$

= 7.065

Volume of cone (larger dish)= 84.78

Volume of sphere(smaller dish)= $\frac{4}{3} \pi r^{3}$

= 14.13

Volume of sphere (larger dish) = 85.17 (approx)

Hence, we get that larger baking dish have approximately same volume.

Therefore, large baking dish of cylinder, cone, sphere will be chosen.
