Question

enter the correct answer. calculate the circumference. formula: c = πd use 3.14 for π. c = ? cm round to the nearest tenth.

Explanation:

Step1: Substitute the values into the formula

Given \(d = 22\) cm and \(\pi=3.14\), substitute into \(C=\pi d\).
\(C = 3.14\times22\)

Step2: Calculate the product

\(3.14\times22=(3 + 0.14)\times22=3\times22+0.14\times22=66+3.08 = 69.08\)

Step3: Round to the nearest tenth

The digit in the hundredth place is \(8\gt5\). So, \(69.08\approx69.1\) (rounded to the nearest tenth)

Answer:

\(69.1\)
