If the following system of equations was written as a matrix equation in the
I aC
A= bd
form AX = C, and matrix A was expressed in the form
1, find
the value of a - b + c + d.
4x+2y=7
5x - 6y=9

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!

unless if u could do my questions, if not i wouldn't want to

step-by-step explanation:

what grade level is this? need to know so i can look in my old textbooks!

the answer is the third / last answer
