Which property allows you to write the expression [(3 +71) + (8 - 61)] + (1+91) as (3 +71) + [(8-61) + (1 +91)]?
DONE

the associative property

Step-by-step explanation:

the associative property allows the numbers to add regardless of how you group the numbers

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!

answer: it's d
