Question

find volume of sphere 3.5 cm

Answer 1

If 3.5 is the radius then
volume= 4/3 pie r×r×r
4/3×22/7×3.5×3.5×3.5=179.66cm3
if we will take the pie 3.14 ,
then,
volume=4/3×3.14×3.5×3.5×3.5=179.50cm3

Answer 2

volume of sphere = 4/3×22/7×r^3
= 4/3×22/7×3.5×3.5×3.5
=4/3×22×0.5×3.5×3.5
=4×22×0.5×3.5×3.5÷3
=539÷3
=179.67
