Answer:
Step-by-step explanation:
surface area of sphere=a
4pir^2=a
r^2=a/4p
r=root(a/4pi)
if radius is doubled
r1=2root(a/4pi)
r1^2=4(a/4pi)
a/a1=(4pia/4pi)/(4pi 4a/4pi)=1/4
so a is increased by 4 times

<h2>Answer</h2>

<h2>Explanation</h2>
1. Use Distance formula
Important to use distance formula in such problems, so keep this formula memorized for future use.
The formula to find distance amongst two points is

2. Plug in the numbers into the formula:
1 -(-1)^2 + 3 - (-3)^2


36 + 4 = 40
3. Find the square root of 40.

Simplify further:

The averge is 25 because the negitive truns into a positive
