The circumference of a circle is found by using the equation: C= 2 x PI x r
Both circles have r = 1
Circumference = 2x 3.14 x 1 = 6.28.
Diameter is 2 times the radius= 2x1= 2
The ratio of the circumference to the diameter = 6.28 / 2 = 3.14 which is the value of PI
Answer the answer is f
Step-by-step explanation:
Answer:
4k - 8
Step-by-step explanation:
Lucy is k years old so we know k is an important part of this problem.
Sister 1 is 3 years younger, so she is k - 3 years old.
Sister 2 is 5 years less than twice Lucy's age therefore, she is 2k (twice Lucy's age) - 5 years old.
Now we have: k + (k - 3) + (2k - 5)
We can simplify like terms with the k's and get 4k. then we add (-3) and (-5) to get 4k - 8.
