The length of the diameter is 2.86 cm rounded to 2 DP
Step-by-step explanation:
The formula of the circumference of a circle is
- C = 2πr, where r is the radius of the circle
- C = πd, where d is the diameter of the circle
∵ The circumference of a circle is 8.97 cm
- We need to find the diameter of the circle, then we will use
the 2nd formula of circumference above
∵ The circumference = πd
- Substitute the value of the circumference in the formula
∴ 8.97 = πd
- Subtract both sides by π
∴ 2.855 = d
- Round it to 2 decimal places (to the nearest hundredth)
∴ d = 2.86 cm

Answer:
C. x>4
Step-by-step explanation:
3/(x-4) > 0
3>0, so
x-4 >0
x > 4
I think it may be that the train is going too fast zoom km 1600 km at the end
Answer 1/4 as a decimal is .25. However, this is 3 1/4, so the answer is 3.25
The passenger has drove 40.8 miles in cab
<em><u>Solution:</u></em>
Given that, To pick up a passenger, the cab company charges a fee of $3.30
Let "x" be the number of miles
For each mile the cab carries the passenger, there is a charge of $2.40 per mile
Therefore,
Total charge = 3.30 + 2.40 ( number of miles )
Total charge = 3.30 + 2.40x
<em><u>Given that passenger is charged $ 101.22</u></em>
Therefore, total charge = 101.22
101.22 = 3.30 + 2.40x
Solve the above expression for "x"
2.4x = 101.22 - 3.3
2.4x = 97.92
x = 40.8
Thus the passenger has drove 40.8 miles in cab
