What is the area of the circle if XY=10ft?Answer options: 25pi ft2, 10pi ft2, 5pi ft2, 20pi ft2
Accepted Solution
A:
Answer: [tex]25\pi\ ft^2[/tex] (First option)Step-by-step explanation: The formula for calculate the area of a circle is the one shown below: [tex]A=r^2\pi[/tex] Where r is the radius of the circle. XY is the diameter. Then the radius is: [tex]r=\frac{10ft}{2}\\r=5ft[/tex] Substitute values into the formula shown above. Therefore, the area of the circle is: [tex]A=(5ft)^2\pi \\A=25\pi\ ft^2[/tex]
