Answer 2

Step-by-step explanation:

since volume of sphere=4/3piR^3

where 'R' is radius of sphere since here diameteris28cm then radius should be half the diameter since radius R =D/2=28/2=14cm

by putting pi=22/7and R=14cm in our formula and solving we can get required volume of sphere as:

V=4/3 ×22/7 ×14×14×14

=4/3 ×22×2×196

=176/3 ×196

=11498.6666667 cubic centimeter.
