Question

the surface area of a sphere is 2464 cm 2 find is volume.

Answer 1

surface area of sphere =4*pi*r^2---(1)
given surface area=2464cm^2---(2)
(1)=(2)

4*pi*r^2=2464
r^2 =(2464*7)/(3*7)
after cancellation
r^2=(14)^2
r=14cm

volume =4/3*pi*r^3
= 4/3**22/7*14*14*14
=11498.66cm^3

Answer 2

Answer:surface area of sphere =4*pi*r^2---(1)

given surface area=2464cm^2---(2)

(1)=(2)

4*pi*r^2=2464

r^2 =(2464*7)/(3*7)

after cancellation

r^2=(14)^2

r=14cm

volume =4/3*pi*r^3

= 4/3**22/7*14*14*14

=11498.66cm^3
