A = πr²

A=π(7.6²)

A= 57.76 π OR 181.37

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.
