Question

find the volume of the sphere whose surface area is 154 cm^2

Answer 1

Hey folk..

Here's your answer..

____________________________________________

$4\pi \: r {}^{2} = 154 \\ \pi \: r {}^{2} = 154 \div 4 \\ \pi \: r {}^{2} = 38.5 \\ r {}^{2} = 38.5 \div 3.14 \\ r {}^{2} = 12.26 \\ r = 3.6$

$volume = 4 \div 3 \times 22 \div 7 \times 3.6 \times 3.6 \\ volume = 54.30cu \: cm$
