A standard dartboard has a diameter of 18 in. What is its area to the nearest square inch?

Reptile [31]

The meaning of the area is the measurement of a surface in this case a circle, which can be find by using the formula $A= \pi r^{2}$ , where r is equal to the radius of the circle.

In this exercise is given that the diameter of a standard cardboard is 18 inches or a radius of 9 inches and it is asked to find its area. Therefore, to find the area of the circle you should substitute the value of the radius into the previous mention formula.

$A= \pi r^{2}$
$A= \pi (9 in)^{2}$
$A= \pi (81 in^{2})$
$A=254.47 in^{2}$

The area of the standard dartboard is 254.47 square inches or 254 square inches.

Which best represents the center of the data set below?

MA_775_DIABLO [31]

Answer: mean = 318.3

Median =330

Mode= 200

Step-by-step explanation:

Mean (average) is the total sum of values in a given a data set ÷ number of values

= 3820/12

Mean= 318.3

Median= midpoint value in a given data set. When the data set is an even number, median is calculated with the 2 middle point values as n1 + n2/2

Step 1: we rearranged the data set from least to highest value to give

200,200,220, 240,300,320,340,360,380,400,420 and 440

Median= 320 + 340/2

=660/2 = 340

Mode is the value with highest frequency in a given data set, from the given question, mode = 200
