Write your answers in terms of 3.14 , and be sure to include the correct units in your answers.

$\huge \bold \orange{answer}$

$\boxed{circumfrence = 2 \times \pi \: \times \: r}$

$d = 10cm \\ r = \frac{10}{2} = 5cm \\ circumfrence = 2 \times 3.14 \times 5 \\ \boxed{ circumfrence = 31.4cm}$

Answer 2

Answer:

circumference=2πr

2×3.14×5

10×3.14

=31.4cm
