Answer:
50.24 in.
Step-by-step explanation:
Step 1: Define/explain/formula.
To find the area of a circle, multiply the radius by itself twice, then multiply the product by pi.
Definitions:
- The diameter is the length through the center.
- The radius is half of the diameter.
- The area of a circle is the amount of interior space enclosed by a circle.
- The circumference of a circle is the distance around the circle.
- 'π' means pi.
[tex]a=\pi r^2(3.14*radius*radius)[/tex]
Step 2: Solve.
The radius of this circle is 4.
Now, we simply plug the numbers into the formula.
[tex]\pi4^2(3.14*4*4)=50.24[/tex]
Step 3: Conclude.
Therefore, the area of this circle is 50.24 in.
