X= pi/4 +k(pi)
(This may not be correct sorry)
Answer:
Step-by-step explanation:
An estimate helps you place the decimal point because when you place 3.7 and 5.1 to multiply you have to count how many spaces of numbers there are. So the answer is 18.87.
We know that,
diameter is twice the radius, I.e d = 2r
Now d = 2(8)ft = 16 feet
2x+x=36
Kim's Sister age
2x+x=36 Add "x and 2x"
3x=36 Divide both sides by 3
÷3 ÷3
x=12
Kim's sister is 12 years old
Soo....
Multiply that by two to get Kim's age
12•2=24 Kim is 24 years old.
