Enter you answer and show all the steps that you use to solve this problem in the space provided. estimate the area of the circle with a radius of 28 cm. use for π.

me! i've been stuck on this and have had it overdue for over 2

you so much, have a great day < 3

estimate:2571.4

actual:2464

Step-by-step explanation:

1) Area of a circle formula:

pi*r^2

pi=22/7

radius=28 cm

so

22/7*28^2=

22/7*784/1=17248/7

17248/7= 24694

THIS IS THE EXACT VALUE

EStimate is

20/7*30^2=

20/7*900=18000/7

2571.4

2464 AND 2571.4 ARE CLOSE ENOUGH SO I WOULD USE 20/7*30^2 AS MY ESTIMATE HOPE THIS HELPS!

see below

step-by-step explanation:

7.   there are 10 data points in the set.   the middle point is between 5 and 6.   the middle point in the top half is 8   and the middle point in the bottom half is 3. to find the iqr , take point 8 and subtract point 3

mid term   point 8 = 100   point 3 = 88

iqr = 100-88 = 12

final   point 8 = 93   point 3 = 78

iqr = 93 - 78 = 15

the final has the greatest iqr

6.   b - there is a high data value that causes the data set to be asymmetrical for the males: the data for males are high and asymmetrical .   there is an outlier for the males that skews the data

5.   the   iqr is a better measure of spread for the movies and basketball games.   since the basketball game has an outlier, we do not want to use standard deviation for measurement.  

3.   the exam median is much higher than the class median.   the median line is farther to the right on the exams

2.   there is no way to tell what the means are from the box and whisker plots.
