Smallest number 0.0292,0.062,0.623,0.844

0.0292

Step-by-step explanation:

It comes down to 0.062 and 0.0292 and 0.0292 has the smaller place value

it happens during combustion and impacts the environment because the plants and trees take in that and it can cause them to die.

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!
