ΔABC has three sides with these lengths: AB = 9, BC = 40, and CA = 41. What is the value of cos C?

kotykmax [81]

Answer:

$cos(C) =\frac{40}{41}\\\\cos(C)=0.976$

Step-by-step explanation:

To find the $cos (C)$ we must use the cosine theorem.

The cosine theorem says that:

$c^2 = a^2 +b^2 -2abcos(C)$

In this case:

$c=AB = 9$

$b=CA = 41$

$a=BC = 40$

So

$9^2 = 40^2 +41^2 -2(40)*(41)cos(C)$

$9^2- 40^2- 41^2 =-2(40)*(41)cos(C)$

$cos(C) = -\frac{9^2- 40^2- 41^2}{2(40)*(41)}$

$cos(C) =\frac{40}{41}\\\\cos(C)=0.976$

A can holds 753.6 cubic centimeters of juice. The can has a diameter of 8 centimeters. What is the height of the can? Use 3.14 f

devlian [24]

Answer:

15 cm

Step-by-step explanation:

The volume of a cylinder is given by

... V = πr²h

Then

... h = V/(πr²)

Substituting the given dimensions, you have

... h = (753.6 cm³)/(3.14·(4 cm)²) = 15 cm
