Standard deviation is the square root of a non-negative number. It will NEVER be negative.
Depreciation = (Cost - Residual)/Useful Life
Cost = $48,000
Residual = $9,000
Useful Life = 15 years
Depreciation = (48,000-9,000)/15
Depreciation = 39,000/15
Depreciation = $2,600
The refrigerator will depreciate at $2,600 a year.

We know, Circumference of a Circle = 2πr
In mathematical form, You can write it as:
2πr₁ = 3(2πr₂)
2π(12) = 6πr₂
24π = 6πr₂
r₂ = 4 m
In short, Your Answer would be: 4 meter
Hope this helps!
