Answer:
~37.70 inches
Step-by-step explanation:
The circumference is π x diameter, so if the diameter is 12, the circumference is π x 12=12π
12π is approximately 37.70
Answer:
x= <u>k+9</u>
4
Step-by-step explanation:
4x-9=k
add nine to each side
4x=k+9
divide each side by 4
x=<u>k+9</u>

x = Alicia's age
Amy is 8 years older than twice her cousin Alicia's age so Amy's age = 2x + 8
Sum of their ages is less than 32
x + 2x + 8 < 32
3x + 8 < 32
3x <24
x < 8
So Alicia's age is greater than 0 but less than 8 years old
(0 < x < 8)
Answer:
A) 0 < x < 8
