Step-by-step explanation:
K=12 if you want explanation i will
4/5 x55
=4/5*55/1
=(4*55)/(5*1)
=220/5
=44/1
=44

R u in geometry 1?
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.
