Answer with Step-by-step explanation:
Volume of sphere= [tex]\dfrac{4}{3}\pi\ r^3[/tex]
[tex]\dfrac{4}{3}\pi\ r^3= 36\pi[/tex]
Dividing by 4π on both sides, we get
[tex]\dfrac{1}{3}r^3= 9[/tex]
Multiplying by 3 on both sides, we get
[tex]r^3=27\\\\r^3=3^3\\\\r=3[/tex]
Hence, radius of sphere is 3 ft
Surface Area of sphere= 4πr²
=4×π×3²
= 36π ft²
Hence, surface Area of sphere is:
36π ft²
