Step-by-step explanation:
<h2>Given that :</h2>
- The radius of a circle is 2.9 in.
<h2>to find :</h2>
- Find the circumference to the nearest tenth.
<h2>formulas used :</h2>
- circumference = 2 × π × r
where,
<h2>explanation :</h2>
⟼ c = 2πr
⟼ c = 2 × 22/7 × 2•9 inches
⟼ c = 2 × 3•14 × 2•9 inches
⟼ c = 6•28 × 2•9 inches
⟼ c = 18•21 inches.
<h2>Round to the nearest tenth :</h2>
⟼ c = 18•21 inches
⟼ c = 20 inches
∴ circle circumference is 20 inches .
