Answer: 94.99 in^2
Step-by-step explanation: The equation for the area of a circle is A=πr^2. To solve this, we need to find the radius. The diameter is the whole circle, whole the radius is half. So divide the diameter by 2.
11/2 = 5.5
The radius is 5.5 inches. Plug the radius into the equation.
A=π5.5^2
Square the 5.5 first. You will get 30.25.
A=π30.25
Plug in 3.14 for pi.
A=3.14 x 30.25
Multiply.
A=94.985
Round to the nearest hundredth.
A=94.99
The area of the circle is 94.99 in^2.
