Answer:
Option B = 25.5 ft
Step-by-step explanation:
Circumference = 80 ft
C = 2πr
80 = 2 * (22/7) * r
80 = (44/ 7) * r
So, Radius (r) = 80 * (7/44)
= 12.72 Feet
--> Diameter = 2r = 2 * 12.72
= 25.45 Feet
Therefore, Answer = Option B = 25.5 Feet (Round off)
Answer:
\bf xy=1\iff y = \cfrac{1}{x}\iff y = x^{-1}\\\\ -----------------------------\\\\ \cfrac{dy}{dt}=-x^{-2}\cdot \cfrac{dx}{dt}\impliedby \textit{using the chain-rule} \\\\\\ \left. \cfrac{dy}{dt}=-\cfrac{\frac{dx}{dt}}{x^2} \right|{ \begin{array}{llll} x=2\\ \frac{dx}{dt}=-2 \end{array}}\implies \cfrac{dy}{dt}=-\cfrac{-2}{2^2}
