The answer to this question is:
A circle is growing so that the radius is increasing at the rate of 2cm/min. How fast is the area of the circle changing at the instant the radius is 10cm? Include units in your answer.?
✔️I assume here the linear scale is changing at the rato of 5cm/min
✔️dR/dt=5(cm/min) (R - is the radius.... yrs, of the circle (not the side)
✔️The rate of area change would be d(pi*R^2)/dt=2pi*R*dR/dt.
✔️At the instant when R=20cm,this rate would be,
✔️2pi*20*5(cm^2/min)=200pi (cm^2/min) or, almost, 628 (cm^2/min)

Answer:
540
Step-by-step explanation:
No matter what the shape, the total amount of degrees in the interior angles in a pentagon is 540. Hope this helps!
To write 8/33 as a decimal you have to divide numerator by the denominator of the fraction.
<span>We divide now 8 by 33 what we write down as 8/33 and we get 0.24242424242424 </span>
<span>And finally we have: </span>
8/33 as a decimal<span> equals </span><span>0.24242424242424</span>
14 or 14.04 if you want to be more specific
