Sam wants to inscribe a square in a circle using only a compass and straightedge. he will first construct a circle and locate its center. he will then perform the following steps. step 1: use the straightedge to draw a diameter of the circle. step 2: copy the length of the diameter and construct another diameter. step 3: join the points of intersection of the endpoints of the diameters and the circle. what is the error in sam's steps?

Hi!

The error Sam made was in Step 2. The reason is because to make a square, the second diameter to be constructed cannot just be constructed in any method. It has to be perpendicular to the other, so the endpoints of the diameters and the circle are equal distances apart from each other.

If the diameter isn't perpendicular to the other, then it could make a rectangle instead.

Hope this helped!

256π units²   (answer b)

step-by-step explanation:

the formula for the surface area of a sphere of radius r

is             a = 4πr²

and so, if r = 8 units, then the surface area is:

a = 4π(8 units)² = 256π units²   (answer b)

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all
