radius of the sphere is​

Answer 1

Answer:

21 cm

Step-by-step explanation:

Answer 2

$volume \: of \: sphere = volume \: of \: cuboid \: \\ \\ = 4\pi {r}^{3} = 49 \times 33 \times 24 \\ \\ = {r}^{3} = \frac{49 \times 33 \times 24 \times 3 \times 7}{4 \times 22} \\ \\ = {r}^{3} = 49 \times 3 \times 3 \times 3 \times 7 \\ \\= r = 21cm$
