I need help with these questions

a.

This question is a rather odd way to ask you to find the radius of a circle from its area.

A = π r²

40000 = π r²

r² = 40000/π

r = √(40000/π)

r ≈ 112.8379

 113 miles

b.

C = 2 π r

754 = 2 π r

r = 754/2π = 377/π

A = π r² = A = π (377/π)² = 377²/π

A ≈ 45241.0658

45241 square miles

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.

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
