Question

Help me please im not good at math!

Answer 1

12 ft^2

Explanation:

Since the formula to find the area of a circle is already up, we can use that to solve the question.

The image gave us the value of the radius right away, so the question will be a lot easier to solve.

--> The reason why the radius is needed is that the 'r' in the formula means radius. We need the value of the radius to find the area of the circle.

Now, we can just replace r with 2.

--> A = 4
`\pi`

Since the question told us to replace
`\pi` with 3, we can do that.

--> A = 4 x 3

--> A = 12

We can conclude that the area of the circle is 12 ft^2.

Answer 2

12 square ft

Explanation:

As given in the picture, the formula for the area of circles is A = pi*r*r. Since the radius is 2 ft and pi is approximately 3, A = 3*2*2 = 12 square ft.
