Answer:
Solution given:
diameter=14cm
radius [r]=14/2=7cm
now
area of semi circle or shaded region: ½πr²=½(3.14*7²)=76.93cm²[approximately]
Answer:
1. A
2. A
Step-by-step explanation:
Im pretty sure that is correct
Answer:
Step-by-step explanation:i think uyou should add$26,0000 +3.5%=then get your answer
fro the next problem o think you should do $231.55 - $2,200=then get youur answer, that answer will probably be the extra that deena has to pay
The triangle ACD is the right angle since it is a triangle in a semicircle. The length of AC from the diagram is 21.9feet
<h3>Application of pythagoras theorem</h3>
The theorem states that the square of the hypotenuse is equal to the square of the other two sides
From the given circle, the triangle ACD is right angle since it is a triangle in a semicircle
Given the following
Hypotenuse = 26 feet = CD
Base side = AD = 14ft
Required
Length AC
Use the theorem
26^2 = 14^2 + AC^2
AC^2 = 676 - 196
AC^2 = 480
AC = 21.9feet
Hence the length of AC is 21.9feet

Answer:
<em>95% confidence interval for the proportion of blocks that are sufficiently strong</em>
<em>(0.83913 , 1.02293)</em>
Step-by-step explanation:
<u><em>Step:-1</em></u>
Given that the sample size 'n' = 29 blocks
<em>Estimate proportion </em>
<u><em>Step:-2</em></u>
<em>95% confidence interval for the proportion of blocks that are sufficiently strong</em>
(0.93103 - 0.0919 , 0.93103 +0.0919)
(0.83913 , 1.02293)
<u><em>Final answer</em></u>:-
<em>95% confidence interval for the proportion of blocks that are sufficiently strong</em>
<em>(0.83913 , 1.02293)</em>
