16 cm and 8 cm respectively Find the volume and

the outer surface area of hollow sphere.
Don't post irrelevant answers​

Answer 1

Step-by-step explanation:

1) the volume V of a spherical she'll whose outer and inner radii R and r respectively is given by...

.V= 4/3π(R^3-r^3) cubic units

=( 4/3)×(22/7)×(16^3-8^3)

= 4/3×22/7×8×448

=4/3×22/7×8×64÷3

= 15018.666666 cm^3

2)If R and r are outer and inner radii of hemishpherical shell then outet surface area = 4πR^2 square units

= 4×22/7×16×16

=3721.14 cm^2
