Question

Fiona draws a circle with a diameter of 14 meters. What is the area of Fiona’s circle?

Answer 1

Answer:

A ≈ 153.94 meters

Step-by-step explanation:

area area equals pi r squared. radius is half of the diameter. Half of 14 meters is 7 meters.

7 meters pi r squared is about 153.94 meters.

that would be my answer

Answer 2

Answer:

The area of the circle is $153.94meters^2$

Step-by-step explanation:

The formula for the area of a circle is : $\pi *radius^{2}$

To work this out you would first need to divide the diameter of 14 by 2, this gives you 7. This is in order for us to calculate the radius. The radius of a circle is the length from one side to the centre.

Now that we know the radius the next step is to multiply pi by the radius of 7 squared, this gives you 153.94. This is because in order for you to calculate the area you would substitute the values into the formula.

1) Divide 14 by 2.

$14/2=7$

2) Multiply pi by 7 squared.

$\pi *7^2=153.94 meters^2$
