TSA of hemisphere = 3πr²
462 = 3×22/7×r²
r² = 462×7/66
r² = 49
r = ✓49 = 7cm
Volume of hemisphere = 2/3πr³ = 2/3×22/7×7×7 = 2×22×7/3 = 102.66 cm³
HENCE,
THE VOLUME OF HEMISPHERE = 102.66CM³
462 = 3×22/7×r²
r² = 462×7/66
r² = 49
r = ✓49 = 7cm
Volume of hemisphere = 2/3πr³ = 2/3×22/7×7×7 = 2×22×7/3 = 102.66 cm³
HENCE,
THE VOLUME OF HEMISPHERE = 102.66CM³
