Question

find the surface area and volume of a sphere whose diameter is 3 cm in terms of Pi

Answer 1

⭐Hey there!!!

◆Given that:

=> diameter(d) = 3cm

=> radius(r) = 3/2 cm

◆surface area of sphere(A) =4πr^2

= 4π(3/2)^2

= 9π cm^2

_________________________

◆ Volume of sphere(V) = 4/3 πr^3

=4/3 π(3/2)^3

=4/3 π 27/8

= 9/2 π

=4.5π cm^3

___________× ____________

⭐Hope it will help you

Answer 2

DIAMETER = 3cm
RADIUS = 1.5cm


SURFACE AREA OF SPHERE = 4π r ^2
= 4 × π × 3 × 3
= 4 × π × 9
= 36π m^2


VOLUME OF SPHERE = 4/3πr ^3
= 4/3×π× 15/10×1.5×1.5
=2×π× 1.5×1.5
= 2×π×2.25
= 4.5 π cm^
