your answer
for (a)
Bcz tennis ball is sphere,
sphere volume =4/3πr³=........here r= 7/2= 3.5 and
volume = 4× 3.14×3.5×3.5×3.5/ 3
Volume = 179. 6 cm^3
for (b)
Given diameter in meter =0.07m
r=d/2
=0.07/2
volume =4/3πr³
=4/3*22/7*(7/200)³
=179/1000000
=0.000179 m^3
or you can directly convert cm answer in meter
