Question

A circle with the diameter of 40 inches. what is the area?

Answer 1

Answer:

A= 1256

Step-by-step explanation:

The formula for area of a circle is $A=\pi r^{2}$

1. Diameter is DOUBLE of radius, so the diameter must be divided by 2. 40/2 = 20.

2. Then, plug in the values into the area formula. A= 3.14$(20^{2})$

3. Solve. A= 1256. (Remember that 20 squared is 20x20)
