Answer:
<h3>Area of a circle in terms of radius:</h3>
Area = π·r^2 = 3.14·9.5^2 = 283.5 square meters(*)
Area of a circle in terms of diameter:
Area = π·(d/2)^2 = 3.14·(19/2)^2 = 3.14·(9.5)^2 = 283.5 square meters(*)
Area of a circle in terms of circumference:
Area = C^2/4π = 59.69^2/4π = 3562.9/(4·3.14) = 3562.9/12.56 = 283.5 square meters(*)
(*) 283.52873698648 meters, exactly or limited to the precision of this calculator (13 decimal places).
Note: for simplicity, the operations above were rounded to 2 decimal places and π was rounded to 3.14.

The method for computing a z-score is , where x is the crude score, is the mean population, and seems to be the <em><u>standard population difference.</u></em>
- The Z value of x is a number are defined where SD is the standard deviation.
- Here, we consider series as scores of students of colleges in New Zealand for their artistic abilities.
following are the calculation of the Z scores:
Using formula:
