Volume of sphere with surface area - Sphere - Mensuration problem solver

The surface area of a sphere is 1386 sq.cm. Find its volume.

volume of sphere with surface area

surface area = 1386
r =  sqrt( ( SA )/ ( 4 * PI ))
radius = sqrt( ( surface_area )/ ( 4 * PI ))
radius = 10.5
So the radius is 10.5
V =  (4/3) * PI * r ^ 3
volume = (4/3) * PI * 10.5 ^ 3
volume = 40
So the volume is 40

Sphere :

A three dimensional object shaped like a ball. Every point on the surface has the same distance from the center.

Sphere Formulas :

C =  2 * PI * r

d =  r * 2

r =  d / 2

V =  (4/3) * PI * r ^ 3

SA =  4 * PI * r ^ 2


where,

d = diameter
C = circumference
r = radius
V = volume
SA = surface area
