Answer:

50.24 units squared

Step-by-step explanation:

The formula for finding area using radius is A = πr^2.

The radius equals diameter/2.

So, r = 8/2 = 4.

Plugging that value in, the equation becomes A = π(4)^2.

Simplifying π to 3.14, the equation becomes A = 3.14(4)^2

Solving 4^2, the equation becomes A = 3.14*16

Solving 3.14*16, the equation becomes A = 50.24.

Therefore, the final answer is 50.24 units squared.

Answer: 50.24

Explanation: The formula for the area of a circle is r^2. So to find it, you have to do 3.14xradius^2. Since you don’t have the radius yet, you can find it by dividing the diameter by 2, which will give you 4 (because 8÷2=4). So all you have to do now is do 3.14x4^2, which is 50.24.
Have a great day!
