Answer:
[tex]\large\boxed{S.A.=4500\pi\ in^2\approx14130\ in^2}[/tex]
Step-by-step explanation:
The formula of a surface area of a ball (sphere):
[tex]S.A.=\dfrac{4}{3}\pi R^3[/tex]
R - radius
We have R = 15in. Substitute:
[tex]S.A.=\dfrac{4}{3}\pi(15^3)=\dfrac{4}{3}\pi(3375)=4500\pi\ in^2[/tex]
If you want to get an approximation, then:
[tex]\pi\approx3.14\\\\S.A.\approx(4500)(3.14)=14130\ in^2[/tex]
