The volume of the sphere is:
V = 4 / 3πr ^ 3
Deriving we have:
V '= (3) (4/3) (π) (r ^ 2) (r')
From here, we clear the value of r ':
r '= (V') / ((4) (π) (r ^ 2))
Substituting values:
r '= (2π) / ((4) (π) ((5) ^ 2))
r '= (2π) / ((4) (π) (25))
r '= (2π) / (100π)
r '= 1/50
Then, the surface area of the sphere is:
A = 4πr ^ 2
Deriving we have:
A '= 8πrr'
Substituting values:
A '= 8π (5) (1/50)
Rewriting:
A '= (40/50) π
A '= (8/10) π
A '= (4/5) π
Answer:
The surface area of the sphere is decreasing at:
(A) 4pi / 5

Answer:
1811.6
Step-by-step explanation:
647x28
18116
move once to the left bc of the point in 64.7
1811.6
I would help you but i don’t know what the answer is
To find a number 10 times smaller than 62 simply move the decimal point one place to the left.
The decimal point in 62 is at the end of the number. 62. becomes 6.2 if we move the decimal one place back.
