Question

The radius of a sphere is 4y. Determine its volume, giving the answer as an exact simplified expression in terms of y

Answer 1

267.95 y^3 or we can keep it like 85.333πy^3

Explanation:

Radius of the Sphere is 4y

Volume of sphere = (4/3)πR^3, where R is the radius of sphere.

Therefore, (4/3) *π*(4y) ^3

= [(256/3) y^3]π

=85.333πy^3

=267.95y^3 (Ans)
