To convert radians to degrees multiply by 180/pi

so 4 rads  = (180* 4) / pi   degrees

Answer:

4radians=229.29degress

Step-by-step explanation:

We have to convert radians to degrees, thus in order to convert radins to degree, the radians should be multiplied with \frac{180}{\pi}.

Thus, conversion of 4radians to degrees is as follows:

4radians=4{\times}\frac{180}{\pi}

Using the value of π=3.14, get

4radians=4{\times}\frac{180}{3.14}

4radians=4{\times}57.32

4radians=229.29degress

1. Sort the numbers into 2 groups, rational or irrational. Write the numbers in the appropriate bubble.
rodikova [14]

Answer:

[see below]

Step-by-step explanation:

  • All natural numbers, whole numbers, integers, fractions (with integers), and numbers with terminating or repeating decimals are rational.
  • Irrational numbers cannot be written as fractions with integers. This includes non-germinating and non-repeating decimals.

Rational Numbers:

  • 0.8
  • 64
  • 0 (it can be written as \frac{0}{1})
  • 32
  • -19
  • -100
  • 3
  • 7
  • 175
  • 2
  • 6
  • 12.67
  • 1121
  • 12
  • 5
  • 3/7

Irrational Numbers:

  • 2.343443444...
  • π

Hope this helps.

Find the volume of the cylinder. Use 3.14 for Pi. Round your answer to the nearest hundredth.the height is 13 and the radius is
NikAS [45]

Answer:

The volume of the cylinder is 2002 square units.

Step-by-step explanation:

It is given that,

Height of the cylinder, h = 13 units

Radius of the cylinder, r = 7 units

We need to find the volume of the cylinder. The formula of the volume of cylinder is given by :

V=\pi r^2 h\\\\V=\dfrac{22}{7}\times 7^2 \times 13\\\\V=2002\ \text{unit}^2

So, the volume of the cylinder is 2002 square units.

Let mu denote the true average number of minutes of a television commercial. Suppose the hypothesis H0: mu = 2.1 versus Ha: mu &
natka813 [3]

Answer:

A. T > 2.539

Step-by-step explanation:

We have a hypothesis test of the mean, with unknown population standard deviation.

The hypothesis are:

H_0: \mu = 2.1 \\\\H_a: \mu > 2.1

From the hypothesis we can see that the test is right-tailed, so the critical value of t should be a positive value.

The degrees of freedom can be calculated as:

df=n-1=20-1=19

The significance level is 0.01, so the critical value tc should be the one that satisfies:

P(t>t_c)=0.01

Looking up in a t-table, for 19 degrees of freedom, this critical value is tc=2.539.
