<span>15/6 + 4/6 +n = 1/6
18/6 = n
n=3

Instantaneous rate of change = S'(r) = 8πr
S'(8) = 8π(8) = 64π
Therefore, the instantaneoud rate of change of the <span>surface area with respect to the radius r at r = 8</span> is 64π
Distance around a circle is CIRCUMFERENCE
DIAMETER*PI=CIRCUMFERENCE
In order to find the answer, you can use-
1/4x=6
In order to get the answer, you multiply 6 by the denominator.
6x4=24
Then, you'd divide the solution of that part by the numerator.
24 divided by 1 equals 24.
Therefore, the final answer would be 24.
