Question

What is the surface area of a sphere with a diameter of 12 centimeters? (Use 3.14 for π .) 1,808.64 cm 2 452.16 cm 2 150.72 cm 2 301.44 cm 2

Answer 1

Sphere Surface Area = PI * diameter²
Sphere Surface Area = 3.14 * 12*12
Sphere Surface Area = 452.16 square centimeters

Answer 2

Answer: The surface area is,

`452.16\text{ square cm}`

Explanation:

We know that,

The surface area of a sphere is,

`A=4\pi (r)^2`

Where, r is the radius of the sphere,

Given,

The diameter of the sphere = 12 cm,

So, the radius of the sphere,

`r= (Diameter)/(2)= (12)/(2) = 6\text{ cm}`,

Hence, the surface area of the given sphere is,

`A=4\pi (6)^2`

`=4* 3.14* 36` (
`\pi` = 3.14 )

`=452.16\text{ square cm}`
