Exam-Style Question on Error Bounds
A mathematics exam-style question with a worked solution that can be revealed gradually
Question id: 513. This question is similar to one that appeared on a GCSE Higher paper in 2019. The use of a calculator is allowed.
Ralph used his calculator to work out the value of C, the circumference of a circle. Unfortunately he put his banana down on his desk so that it covered most of the calculator screen. All that can be seen are the first two digits of the answer.
Complete the error interval for C$$. . . . . . . . . . \le C \lt . . . . . . . . . .$$
