given that
tsa of the sphere = 616
4πr² = 616
r² = 616×7/22×4
r² = 49
r = 7cm
then the volume of the sphere = 4/3πr³
= 4/3×22/7×7×7×7
= 1437.33cm
tsa of the sphere = 616
4πr² = 616
r² = 616×7/22×4
r² = 49
r = 7cm
then the volume of the sphere = 4/3πr³
= 4/3×22/7×7×7×7
= 1437.33cm

TSA = 616
4πr² = 616
r² = 49
r = 7 cm
VOLUME = 4/3πr³ = 4/3*3.14*7*7*7 = 1437.33 cm
4πr² = 616
r² = 49
r = 7 cm
VOLUME = 4/3πr³ = 4/3*3.14*7*7*7 = 1437.33 cm
Mark as brainliest plzzz
