Answer:
Notice that for any increase, x * l or x * r, in length or radius, the increase in surface area is x squared (x2) and the increase in volume is x cubed (x3).
Step-by-step explanation:
It’d be 2
250 ÷20= 12.5
25 ÷2=12.5
20% of a number is 1/5th of it so 50 × 5 is 250
Let us assume the common ratio to be = x
Then
(1 * x) + (4 * x) = 50
x + 4x = 50
5x = 50
x = 50/5
= 10
So from the above deduction, we get the common ratio to be equal to 10
Then
The smallest number = 1 * x
= 1 * 10
= 10
-4.58
full number : -4.585786438
