5x10^5
0.000023 + 0.0000078= 0.0000308
3.8x10^-6
i think
sorry if wrong but i dont know the second one that well
The surface area of a sphere is

where r is the radius;
The circumference is

so that

using this value we can evaluate the surface area of 1 ball as:

For 100 ball you get:
Answer:
D
Step-by-step explanation:
Answer: 21 is your range
hope this helps
Step-by-step explanation:
To find the range, subtract the smallest number in the set from the largest
Answer:
The slope is 2. (m=2).
Step-by-step explanation:
y+5=2x+2
y+5-5=2x+2-5
y=2x-3
Equation is y=2x-3.
y=y-intercept
x=slope
Hence, the slope is 2.
Hope this helps and stay safe!
