Question

Find the surface area of a sphere with a radius of 12 cm. Approximate 3.14 and round your answer to the nearest hundredth

Answer 1

588.57

Explanation:

4xpix12^2

Answer 2

the equation to find a spheres surface area is 4 pi R ^2
and this works in any order

4 * 12 is 48 (4 * R)

48^2 is 2304 ((4 * R)^2)

the exact answer is 2304
`\pi`

the full answer is 7234.56 (((4 * R)^2)
`\pi`)
