Answer:
it's rational
Step-by-step explanation:
Answer:
2/π ≈ 0.637 m/s
Step-by-step explanation:
The rate of change of area with respect to time is ...
A = πr²
dA/dt = 2πr·dr/dt
Filling in given values in the above equations, we can find r and dr/dt.
25π = πr² ⇒ r = 5
20 = 2π·5·dr/dt
dr/dt = 20/(10π) = 2/π . . . . meters per second
The radius is increasing at the rate of 2/π ≈ 0.637 meters per second.
I take it that the actual total is 538. If it really is 538538 leave me a note.
Let the first number = x
Let the second # = 44x
Let the third # = 100x
Equation
x + 44x + 100x = 538 Add the left side. All terms are part of the total.
145x = 538 Div By 145
x = 538/145
x = 3.71
Check
First number = 3.71
Second # = 44*3.71 = 163.24
Third number = 100*3.71 = 371
Total these 3 numbers 537.95 The very tiny difference is due to rounding.
