Sam, Carla and Sarah spent an afternoon collecting sea shells. Sam collected 11.If we add the number of sea shells collected by Sam and Carla, the total would be 24.If we add the number of sea shells collected by Carla and Sarah, the total would be 25 shells. How many shells did each one collect?​

Sam collected 11, Carla collected 13 and Sarah collected 14.

Step-by-step explanation:

24 - 11 = 13

25 - 11 = 14

You basically just subtract the total of what Sam got with the total they came to.

Sam has 11

Carla has 13

and Sarah has 12

11-24=13

and 13-25=12

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!
