<h3>The radius is 7 cm</h3>
Step-by-step explanation:
Volume of a sphere is given by

where r is the radius
From the question V = 1436 cm³

Multiply through by 3
We have

Divide both sides by 4π


Find the cube root of both sides
![r = \sqrt[3]{ \frac{1077}{\pi} }](https://tex.z-dn.net/?f=r%20%3D%20%20%5Csqrt%5B3%5D%7B%20%5Cfrac%7B1077%7D%7B%5Cpi%7D%20%7D%20)
r = 6.99
We have the final answer as
<h3>r = 7cm</h3>
