Find the area of a regular decagon with an apothem of 5 meters and a side length of3.25 meter. Round to the nearest tenth

topjm [15]

We know that

<span>The regular decagon can be divided into 10 congruent triangles
</span>so
area regular decagon=10*[area of one triangle]

area triangle=b*h/2
where
b=3.25 m
h is the aphotem
h=5 m
area=3.25*5/2----> area=8.125 m²

area regular decagon=10*[8.125]----> 81.25 m²

Area=81.3 m²

the answer is
81.3 m²

The elevation of an underwater cave is -120 feet relative to sea level. A submarine descends to the cave. the submarine rate of

Drupady [299]

Answer:

Time taken by the submarine to reach the cave is 10 seconds.

Step-by-step explanation:

We are given that,

The elevation of the underwater cave = -120 feet.

The rate at which the submarine descends to the cave = -12 feet per second

Thus, we have,

The time taken by the submarine to reach the cave = $\frac{-120}{-12}$ = 10 seconds.

Hence, the time taken by the submarine to reach the cave is 10 seconds.
