Question

(4) Find the length of the median BE of A ABC where A = (10.6
B = (-2, 2) and C = (6. 10).​

Answer 1

Step-by-step explanation:

The figure that each tip of the hands draws is a circle. The formula for the circumference is 2\pi r2πr , where \piπ is pi and rr is the radius.

Solution

The tip of the short hand moves 8\pi8π cm each revolution, while it revolves once each 12 hours.

The tip of the long hand moves 12\pi12π cm each revolution, while the long hand revolves once each hour.

2 days are given to revolve. Hence, 48 hours are given.

The short hand revolves 4 times, so the distance it travels is

\rightarrow 32\pi→32π cm

The long hand revolves 48 times, so the distance it travels is

\rightarrow 576\pi→576π cm

The sum of the distance traveled is

\rightarrow \boxed{608\pi}→

608π
