Factor completely 6x^4y^3 + 21x^3y^2 − 9x^2y.

3xy(2x^3y^2 + 7xy − 3x)
3x^2y(2x^2y^2 + 7xy − 3)
3x^2y3& (2x^2 + 7xy − 3)
3x^2y(2x^2y + 7xy − 3y)

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!
