<h2>
<u>Answer:</u></h2>
Pi = 3.14
Diameter (d) = 86 cm
•°• Radius (r) = 86 ÷ 2 = 43 cm (radius is 1/2 of diameter)
Area of the circle = ?
Formula,
Substitute the value of 'r' & pi in the formula.
⎆ The area of the circle is about <u>5</u><u>8</u><u>0</u><u>5</u><u>.</u><u>8</u><u>6</u><u> </u>cm² (approx.)
Answer: A
Step-by-step explanation: when Constructing a confidence interval, it is important to take note of the margin of error which is given by the formulae below
Margin of error = critical value × σ/√n.
Where n is the sample size.
As we can see that the critical value is a constant and the population standard deviation.
Hence there is an inverse relationship between margin of error and sample size, which implies that a large sample size produces a small margin of error.
If the margin of error is small, it means the sample size will increase the like hood that the sample is a good representation of the population.
