Answer:
Step-by-step explanation:
here is your answer
Calculation steps:
8 and 10 are possible lengths of the third side.
I did 14 divided by 0.007 and its 2000 so he can prepare 2000 capsules
As we knw that the dr/dt = 2
And The area of the circular slick is given by formul
A = (pi)r^2.
Now lets take derivative:
<span>dA/dt=2πrdr/dt
As we knw that radius is 25
so</span><span>dA/dt=2π(25)(2)=100π
which is equal to
=314.16 per minute this is how area is increasing
now for part b
</span><span> t = 4, the radius will have increased to 8 m.
now we will put the values in formula dr/dt
</span>so it will be.dA/dt=2π(8)(2)
=32π
=100.53 is the answer
hope it helps
