What is the surface area of a sphere with a radius of 16 units? a. 288 units2 b. 1024 units2 c. 256 units2 d. 1024 units2?

The surface is .

Step-by-step explanation:

The surface of a sphere is given by the following formula:

In which r is the radius of the sphere.

In this problem, we have that:

A radius of 16 units, so .

So

The surface is .

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
