The radius is found from
... A = πr²
... r = √(A/π) = √(154/π) m ≈ 7.00 m
The circumference is then
... C = 2πr = 2π(7.00 m) ≈ 43.99 m
The circumference is about 44.0 m.
1) When finding a median, order your numerical list from smallest to larger, as so: 2,2,3,4,5,6,8,9.
2) Then start eliminating numbers from each side of the order; (The bolded numbers will be removed.)
2,2,3,4,5,6,8,9
2,3,4,5,6,8,9
2,3,4,5,6,8
3,4,5,6,8
3,4,5,6
4,5,6
4,5
3) Since there is an even number of digits in your list, you will have to add the last two digits and then divide them by two. 4 and 5 are the last numbers standing, (4+5=9)(9/2=4.5) and therefore your answer, would be 4.5, or B.
(2k - 3) / -5 > 7....multiply both sides by -5....eliminating the -5 on the left
and change the inequality sign because ur multiplying by a negative
2k - 3 < 7 * -5
2k - 3 < -35...add 3 to both sides
2k < -35 + 3
2k < - 32...divide both sides by 2
k < -32/2
k < - 16
