Question

The diameter of a circle is 2 miles. What is the circle's area?

Answer 1

Answer:

3.14

Step-by-step explanation:

The Formula for area of a circle is л times r^2. R(radius) is half of D(diameter )in which this case is 1. So 1^2 = 1 times л which is 3.14. 3.14 times 1 = 3.14 as answer.

Answer 2

Answer:

A= 3.14

Step-by-step explanation:

The formula for finding the area of a circle is  A=π r²

The radius = half of the diameter so that makes the radius 1 in this case.

When you plug in the values for the equation you get A= 3.14*1²
