Question

The area of a circle is 3.14 square yards. What is the circle's radius?
Use 3.14 for I.

Answer 1

The area of a circle is given by the formula A = πr², where A is the area and r is the radius. We are given that the area of the circle is 3.14 square yards, so we can plug this value into the formula and solve for the radius:

A = πr²

3.14 = πr²

Dividing both sides by π, we get:

r² = 3.14/π

Taking the square root of both sides, we get:

r = √(3.14/π)

Using a calculator to evaluate this expression, we get:

r ≈ 0.9997 yards

So the radius of the circle is approximately 0.9997 yards.

Approximately equal to 1 !

Answer 2

Answer:

r = 1

Explanation:

The formula for the area of a circle is

A = πr^2,

where A is the area and r is the radius.

Given the area of the circle as 3.14 square yards, we can plug in the value for A and π to get:

3.14 = πr^2

To solve for the radius, we need to isolate r on one side of the equation. We can do this by dividing both sides of the equation by π and then taking the square root of both sides:

r = √(3.14/π)

Using the value of π as 3.14, we can simplify this to:

r = √(3.14/3.14)

r = √1

r = 1

Therefore, the circle's radius is 1 yard
