Question

The volume of a sphere is 8.6 cubic meters. Determine the radius of the sphere. Use 3.14 for π

Answer 1

Answer:

r=1.27m

Step-by-step explanation:

volume of sphere = 8.6 cubic metre

$4 \div 3\pi \: r ^{3} = 8.6$

$4 \div 3 \times 3.14 \times r ^{3} = 8.6$

${r}^{3} = 8.6 \times 3 \div 12.56$

${r}^{3} = 25.8 \div 12.56$

$r \: = \sqrt[3]{2.054}$

$r \: = 1.27m$
