An anthropologist studies a woman's femur that was uncovered in Madagascar. To estimate the woman's height, he uses the equation
Lelu [443]

Answer:

The inequality f>40 represents the length of the femur for which the woman had a height greater than 160cm.

Step-by-step explanation:

The given equation is

h=60+2.5f

Where, h is woman's height in centimeters and f is length of the femur in centimeters.

If woman's height is greater than 160cm, then

h>160

60+2.5f>160

Substract 60 from both sides.

2.5f>100

Divide both sides by 2.5.

f>40

Therefore the inequality  f>40 represents the lengths of the femur for which the woman had a height greater than 160cm.

SA = 2\pi rh+2\pir^2

1. Find the radius.

R = 1/2D

6 x 1/2 = 3

R = 3

2. Plug them in.

SA 2(3.14)(3)(7) + 2(3.14)(3^2)

3. Solve

3 x 7 = 21

21 x 3.14 = 65.94

65.94 x 2 = 131. 88

3^2 = 9

9 x 3.14 = 28.26

28.26 x 2 = 56.52

4. Add them together.

131.88 + 56.52 = 188.4

Answer: 188.4 square millimeters
