The diameter of a sphere is 12 cm. Calculate, correct of the nearest cm\(^3\), the volume of the sphere, [Take \(\pi = \frac{22}{7}\)]
903 cm\(^3\)
904 cm\(^3\)
905 cm\(^3\)
906 cm\(^3\)
توضيح
Volume of sphere = \(\frac{4}{3}\)\(\pi\)r\(^3\)
diameter = 12cm ⇒ r = 6cm
V. of sphere = \(\frac{4}{3}\) x \(\frac{22}{7}\) x 6\(^3\) \(\approxeq\) 905cm\(^3\)
