Answer:
diameter = 59 .4 cm , volume = 109782 .4 cm³
Step-by-step explanation:
surface area of sphere = 11088 cm²
4 π r² = 11088
4 x 22/7 x r² = 11088
r² = ( 11088 x 7) / ( 4 x 22 )
= 882
∴ r = 29.7 cm
diameter of sphere = 2 x 29.7
= 59.4 cm
Volume of sphere = 4/3 π r³
= 4/3 x 22/7 x 29.7 x 29.7 x 29.7
= 109782.4 cm³
