Step-by-step explanation:
Dr/dt= 8cmM-¹
dA/dt = ?
but A= πr²
so dA/dr =2πr
but recall
dA/dt = dA/dr • dr/dt
dA/dt = 2πr • 8cmM-¹
dA/dt = 2×π×39 ×8 = 624cm²M-1
The answer is 6.6 repeating, so 6.6666...
So first I took 1 and 3/5 and put it into decimal form which gave us 1.6, then I did the same with 3 and 1/3 and got 3.3 repeating, and now I multiply these and get 5.33333 repeating, and now I add the 3 and 1/3rd to get 6.6666 repeating.
C. -5.4 -17.6+12.2= -5.4 because -17.6 goes first in the calculator but also its a negative
Subtract negative = add
88 + 35 = 123
The solution is 123
