Question

The
Radius
of
sphere
is
increased from 7cm
to 7.02 cm.
find
The
Approximate
increase in
Volume.​

Answer 1

Answer:

volume of sphere=4/3πr^2

=4/3(22/7) (49)

=205.34

volume of new sphere=4/3πR^2

=4/3(22/7)(7.02) ^2

=206.50

volume increase=volume of new -volume of old sphere

=206.50-205.34

=1.16cm^3
