Catie charges an initial amount of $5 for babysitting and then $3 per hour. jolisa does not charge an initial amount but charges $4 per hour. solve an equation to find how many hours each girl will have to work to earn the same amount.

they would have to work 32 hours.

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!
