How many one-to-one correspondences exist between A = {1, 2, 3, 4} and B = {a, b, c, d, e}

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!

step-by-step explanation:

answer is : muchas/tipicas

have a nice day!

its the second choice.

step-by-step explanation:

the elements in the range will be 7 less than the elements in the domain.
