What are the inequalities for:
x is less than 8 and greater than 3
x is less than 4 and greater than -2
x is greater than 12 and less than or equal to 17

3 < x < 8

-2 < x < 4

12 < x ≤ 17

Step-by-step explanation:

x is less than 8 and greater than 3

i.e 3 < x < 8

x is less than 4 and greater than -2

i.e -2 < x < 4

x is greater than 12 and less than or equal to 17

i.e 12 < x ≤ 17

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
