If the radius of the sphere is 3.5 inches , then the volume is 130.85 inches³ and the surface area is 153.86 inches² .
In the question,
it is given that , the shape of the exercise ball is a sphere ,
the radius of the sphere is = 3.5 inches ,
the volume of sphere is gives as
Volume = (4/3)πr³
= (4/3)π(3.5)³ ....using π = 3.14
= 130.85 inches³
and Surface Area of the Sphere is = 4πr²
= 4π(3.5)² ....using π = 3.14
= 153.86 inches²
Therefore , If the radius of the sphere is 3.5 inches , then the volume is 130.85 inches³ and the surface area is 153.86 inches² .
