Respuesta :
Sphere Surface Area = PI * diameter²
Sphere Surface Area = 3.14 * 12*12
Sphere Surface Area = 452.16 square centimeters
Sphere Surface Area = 3.14 * 12*12
Sphere Surface Area = 452.16 square centimeters
Answer: The surface area is,
[tex]452.16\text{ square cm}[/tex]
Step-by-step explanation:
We know that,
The surface area of a sphere is,
[tex]A=4\pi (r)^2[/tex]
Where, r is the radius of the sphere,
Given,
The diameter of the sphere = 12 cm,
So, the radius of the sphere,
[tex]r= \frac{Diameter}{2}= \frac{12}{2} = 6\text{ cm}[/tex],
Hence, the surface area of the given sphere is,
[tex]A=4\pi (6)^2[/tex]
[tex]=4\times 3.14\times 36[/tex] ( [tex]\pi[/tex] = 3.14 )
[tex]=452.16\text{ square cm}[/tex]
