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

Explanation:

Step1: Identify values

Given $d = 19$ cm and $\pi=3.14$.

Step2: Apply formula

$C=\pi d=3.14\times19$.

Step3: Calculate result

$3.14\times19 = 59.66$ cm.

Step4: Round to nearest tenth

Rounding $59.66$ to the nearest tenth gives $59.7$ cm.

Answer:

$59.7$ cm
