Answer:

$181.46\text{ cm}^2$

Explanation:

We have been given that the radius of a flying disc is 7.6 centimeters. We are asked to find the approximate area of the disc.

We know that a disc is in form of circle, so we will use area of circle formula to find area of our given disc.

$\text{Area of circle}=\pi r^2$ , where, r represents radius of circle.

Upon substituting
$r=7.6\text{ cm}$ in area formula, we will get:

$\text{Area of flying disc}=\pi(7.6\text{ cm})^2$

$\text{Area of flying disc}=\pi 57.76\text{ cm}^2$

$\text{Area of flying disc}=181.45839\text{ cm}^2$

$\text{Area of flying disc}\approx 181.46\text{ cm}^2$

Therefore, the area of the flying disc is approximately 181.46 square centimeters.
