The length of the longest chord of the circle with radius 2.9 cm is ______.

#### Options

3.5 cm

7 cm

10 cm

5.8 cm

###### Advertisements

#### Solution

The length of the longest chord of the circle with radius 2.9 cm is **5.8 cm**.

**Explanation:**

The longest chord of the circle is the diameter.

Radius = 2.9 cm

So, diameter = 2.9 + 2.9 = 5.8 cm
