find the area of the figure using 3.14 for pi round answer to the nearest tenth and the diameter of the circle is 20 in

The area cut off from the circle is equal to 1/4 of the circle. This means that the area remaining is
1 - 1/4 = 3/4
The formula for calculating the area of a circle is expressed as
Area = πr^2
where
r is the radius of the circle.
From the information given,
r = 10
Area of figure = 3/4 x 3.14 x 10^2
Area of figure =
