spin [16.1K]

Answer:

When circumference = 6.3 then radius =

circumference / (2 * PI) = 6.3 / (6.283) =

radius = 1.0027

Cone Volume = PI * radius ^2  * height / 3

Cone Volume = PI * 1.0027^2 * 17 / 3

= 17.898 cubic meters which rounds to

Two boats leave a marina at the same time. The first boat travels 6 knots at a bearing of N39, and the second boat travels 4 kno
cestrela7 [59]

For the first boat, 6 knots at a bearing of N39, and for the second boat  4 knots at a bearing of S87°W.  the distance of boats at the end of 2 hr and the bearing of 1st to 2nd both is mathematically given as

  • V'=22.93Km
  • B=132°

<h3>What is the distance b/w the boats at the end of 2 hr and the bearing of 1st to 2nd boat?</h3>

Generally,  the Relative speed  is mathematically given as

V=\sqrt{4^2+6^2+2(4)(6)cos(48)}

V=\sqrt{52+48(0.669)}

X=9.17Knots

Hence, distance b/w the boats

V'=9.17Knots*2

V'=18.34

V'=22.93Km

In conclusion, the bearing of 1st to 2nd boa ist

B=39+90+(90-87)

B=132°
