From base camp, a hiker walks 3.5 miles west and 1.5 miles north. Another hiker walks 2 miles east and 0.5 miles south. To the n

levacccp [35]

Answer:

The hikers are 5.9 miles apart.

Step-by-step explanation:

Let O represents the base camp,

Suppose after walking 3.5 miles west, first hiker's position is A, then after going 1.5 miles north from A his final position is B,

Similarly, after walking 2 miles east, second hiker's position is C then going towards 0.5 miles south his final position is D.

By making the diagram of this situation,

Let D' is the point in the line AB,

Such that, AD' = CD

In triangle BD'D,

BD' = AB + AD' = 1.5 + 0.5 = 2 miles,

DD' = AC = AO + OC = 3.5 + 2 = 5.5 miles,

By Pythagoras theorem,

$BD^2 = BD'^2 + DD'^2$

$BD = \sqrt{2^2 + 5.5^2}=\sqrt{4+30.25}=\sqrt{34.25}\approx 5.9$

Hence, the hikers are 5.9 miles apart.

A sphere and a cylinder have the same radius and height. The volume of the cylinder is 27 xft?

attashe74 [19]

Answer:

Volume of sphere = $\frac{2}{3}(27\pi) ft^3$

Step-by-step explanation:

We are given that

Radius of sphere=Radius of cylinder=r

Height of sphere=Height of cylinder=h

Height of sphere=h=Diameter of sphere=2r

Volume of cylinder= $27\pi ft^3$

Volume of cylinder= $\pi r^2 h$

Using the formula

Volume of cylinder= $\pi r^2(2r)=2\pi r^3=27\pi$

Volume of sphere= $\frac{4}{3}\pi r^3$

Using the formula

Volume of sphere= $\frac{2}{3}\times 2\pi r^3=\frac{2}{3}(27\pi)$

Hence, the volume of sphere = $\frac{2}{3}(27\pi) ft^3$
