HELP PLZ! ID. K HOW TO DO THIS! :) (RIGHT ANSWER WILL GET BRANLIEST)

first one it is about 10

Secound one is 4 ÷ (1)=4

the third is x<4

the fourth is 16 ÷(-4)=4

Step-by-step explanation:

1. 34/3.5=9.714 so if rounded its about 10

2. its not going to be negitive so that why its that

3.because its after(it shows in the diagram.)

4. i'm not sure how to explain this one i'm sorry

Here is the

10

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!

you should at least use a calculater
