The formula for the volume of a cylinder of radius r and height h is:

V = pi*r^2*h.

In this case,

V = pi*(40 cm)^2*(130 cm)

  = pi(1600 cm^2)(130 cm) = 208000*pi cm^3

If we use 3.14 for pi, then the volume is V = 653120 cm^3

\pi = 3.14\\r=40cm\\h=1.3m=130cm\\V=\pi r^{2}h\\V=(3.14)(40^{2})(130)\\V=(3.14)(1600)(130)\\V=653120cm^{3}

Can someone give me the answer
Tasya [4]

Take the 4cm side and the 6cm side.

If you hook them together at one end, then there's no way they can reach the ends of the 11cm side.  The farthest they can reach is 10cm.

That's what choice-B says.

Need help asap thanks
Ymorist [56]

Answer:

A

Step-by-step explanation:

for a right angled triangle, the sum of the square of the two sides should be equal to the square of the hypotenuse. If this rule does not hold, the dimensions do not represent the side of a right angled triangle.

The Pythagoras theorem : a² + b² = c²

where a = length

b = base

c =  hypotenuse

4² + 10² ≠ 16²

6² + 12² = 13²

7² + 24² = 25²

8² + 15² = 17²

The statistical test that would be most appropriate determine the answer the researcher is interest in knowing is a chi-square test.

<h3>What is a chi-square test?</h3>

A chi-square test is a statistical test used to test the relationship between categorical variables. It is used to determine the difference between the expected data and the observed data is due to chance.

Chi squared = \frac{(O_{i} - E_{i} )^{2} }{E_{i} }

Where:

  • O_{i} = observed value
  • E_{i} = expected value.

The researcher is interested in knowing if the response to lowering the legal age for drinking alochol (observed value)) varies by gender (expected value). Thus, a chi-square test would be used.
