Sophia wrote 260,880 as (2 times 100,000)+(6 times 10,000)+(8 times 100). what error did sophia make

260,880 as (2 times 100,000)+(6 times 10,000)+(8 times 100).

here Sophia must consider 80 as 8 times 10

so that complete expression becomes

260,880 = (2 times 100,000)+(6 times 10,000)+(8 times 100)+(8 times 10)

then, the surface area of the sphere shown in the image is: 256π sq. units!

step-by-step explanation:

the lateral surface area of a sphere is 2πrh where h=2r.

then:

surface area = 4πr^2.

in this case, r=8 units ⇒ surface area = 4π(8 units)^2. = 256π sq. units!

then, the surface area of the sphere shown in the image is: 256π sq. units!
