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:
Rob won because if dale came in last then hes already marked out but then we have henry and charles. if henry finished ahead of charles that wouldve made him second to last but remember that rob ran faster then henry so rob mustve finished first.

You know that 6 is divisible by 3/ 3 is a factor of 6 (3•2=6) so you could further simply 3/6 using a common factor, more specifically their Greatest Common Factor also known as the GCF
