If the radius of a flying disc is 7.6 centimeters, what is the approximate area of the disc? HELP ASAP
Answer:
\(181.46\text{ cm}^2\)
Step-by-step 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.
