32 divided 10 - 8 divided 2 - 3

-3.8

Step-by-step explanation:

-3.8 i think sorry this is the first one im not sure with.

Step-by-step explanation:

32/10=2.4

3-2=1

2.4-8=5.6

5.6/1=5.6

=-3.8

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!

answer: for each 3 girls there is 2 boys . 3: 2
