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.
Answer:
-1
Step-by-step explanation:
y = -x + 6 the number in front of x is the point slope
so, the answer is -1 because the number in front of x is -1
Answer:
75% .
Step-by-step explanation:
25%, 50%, 75%, 100%
0.67 Since 2 (in the thousandths place) is lower than 5 you round down wich just leaves you with 0.67
What is the inequality sign?!?
