Question

PLEASE HELP! I need this answered ASAP ;-; (Question is shown below in the attachment)

Answer 1

pi units squared

Explanation:

(cant find pi sign)

(pi times r^2)/4

4pi/4

pi

Answer 2

3.14 units²

Explanation:

The key realization here is that this shape is one quarter of a circle.

Therefore, it's area will be
`(1)/(4)` of the whole circle's area.

So, let's first find the area as if this were a whole circle.

The formula is
`\pi r^2`, and we know that the radius, r, is 2. So:

`\pi\cdot2^2\\\\\pi\cdot4\\\\3.14\cdot4\\\\12.56`

Now we need to find one fourth of this, we can do this by dividing by 4.

`12.56/4=3.14`

Hope this helped!
