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,

  • π = 22/7
  • r = 2•9 inches

<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 .
