I believe you just plug in the distance formula:
remove the radical by squaring both sides. then remove the exponents. you'll then have
y equals 39. I'm not entirely sure about this. I hope I answered your question correctly
Step-by-step explanation:
Area of circle = πr², π = 22/7 or 355/133. Here it is said to use '3.14'. I will use the same.
Volume = cross-section area * height
Cross-section area of bigger one = π(3m)²
Volume = π(3m)² * height
= 9π * 5 m³ = 45π m³
Cross-section area of smaller one= π(1m)²
Volume = π(1m)² * height
= π * 5 m³ = 5π m³
Since a large part(cylinder of 1 m is not here):
Required volume = total volume - volume of smaller circle(cylinder)
= 45π - 5π m³
= 40π m³ = 40(3.14) m³
= 125.6 m³
Answer:
a)
<em> you are unwilling to predict the proportion value at your school = 0.90</em>
<em>b) </em>
<em>The large sample size 'n' = 864</em>
<em></em>
Step-by-step explanation:
Given estimated proportion 'p' = 10% = 0.10
<em>Given Margin of error M.E = 0.02</em>
<em>Level of significance α = 0.05</em>
a)
<em> you are unwilling to predict the proportion value at your school </em>
<em> q = 1- p = 1- 0.10 =0.90</em>
b)
<em>The Margin of error is determined by</em>
Cross multiplication , we get
√n = 29.4
<em>Squaring on both sides , we get</em>
<em> n = 864.36</em>
<u><em>Conclusion</em></u><em>:-</em>
<em>The large sample size 'n' = 864</em>
<em></em>

Answer:
The volume of the figure is 51.66 in3
Step-by-step explanation:
sol;
volume of prism=area of trangular base * length of prism
=1/2*b*p*7.2
=1/2*4.1*3.5*7.2
=51.66 in3
