B. 4.5
C. 1.5
D. 6
Answers: 2
![\text{Volume of hemisphere} = \dfrac 23 \pi \times r^3\\\\\implies 56 = \dfrac{2 \pi}3} \times r^3\\\\\implies 56 \times 3 = 2 \pi r^3\\\\\implies r^3 = \dfrac{168}{2 \pi} \\\\\implies r =\sqrt[3]{\dfrac{168}{2\pi}} = 2.99 \approx 3~ cm](/tpl/images/2579/0744/dc5df.png)
