Question

Henry knows that the circumference of a circle is 18 pie inches. What is the area of the circle?

Answer 1

Answer:

254.34

Step-by-step explanation:

This is because A=C2

4π which is 18x18 divided 4x 3.14 which equals 254.34

Answer 2

Answer: 25.5 (using the whole value of )

Explanation: The formula for the area of a circle is: xradius^2. So all you have to do is find the radius. To do that, you have to find the diameter. The formula for calculating the circumference of a circle with the diameter, is: xdiameter. So now, you do the opposite of that: circumference ÷ . That gives you: 5.7, which is the diameter. To find the radius with the diameter, you just divide the diameter by 2. And 5.7 ÷ 2=2.85. Now that you know the radius, you can find the area: x2.85^2=25.5 inches.
