Question

a flying disc has a radius of 10 inches. what is the area of one side of the flying disc to the nearest square inch? use 3.14 as an approximation for π.
1,256 square inches
63 square inches
314 square inches
79 square inches

Explanation:

Step1: Recall the formula for the area of a circle

The formula for the area of a circle is \(A = \pi r^{2}\), where \(r\) is the radius of the circle.

Step2: Substitute the given values into the formula

Given \(r = 10\) inches and \(\pi\approx3.14\). Then \(A=3.14\times10^{2}\).
First, calculate \(10^{2}=100\).
Then \(A = 3.14\times100\).

Step3: Perform the multiplication

\(3.14\times100=314\) square inches.

Answer:

314 square inches
