Download Solution PDFGiven:
Surface area is 124.74 cm2
Formula Used:
Total Surface area of sphere = 4 π r2
Volume of sphere = (4/3)π r3
Radius of sphere = r
Calculation:
Total Surface area of sphere = 4 π r2
⇒ 4 π r2 = 124.74
⇒ r = √(124.74 × 7/88)
⇒ r = 3.15
According to the question,
Volume of sphere = (4/3)π r3
⇒ (4/3) π × (3.15)3
⇒ 130.977 cm3
∴ The volume of sphere is 130.977 cm3
