Write an equation for the n th term of the arithmetic sequence -7,-2,3,8,... . then find a_50 a_50 stands for a sub 50 as in the 50 term.

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!

your answer would be 12
