The figure shows a sphere with diameter 28 cm.
Radius = half of diameter
Radius = half of 28= 14 cm
The formula for volume of sphere is given by :
[tex] V= \frac{4}{3} \pi r^{3} [/tex]
where r is radius of sphere.
Plugging the value of pi =3.14 and r=14cm in the formula,
[tex] V= \frac{4}{3} (3.14) (14)^{3} [/tex]
On solving we get Volume =11488.21 cm³
