Question

Find the area of the shaded portion in the square
assuming the central of each arc is the corresponding central point of the line and the arcs intersect at the center point of the circle

Answer 1

Area= area of sector - area of triangle

Answer 2

I need help finding the area of the triangle

Answer 3

hmmmm do we know anything else... because.. the shaded are is not really circular per se

Answer 4

if you just need the triangle's area, made by the diagonal of the square.
you can get that by just using the pythagorean theorem, or just the 45-45-90 rule

then again, that's not the shaded area though

Answer 5

There's a equation that I have to fill
A=pi - ?
There isn't much info given to me after that

Answer 6

hmm can you post a quick screenshot of the material? I can see the picture..I just dunno what's being requested

I don't think you can use \(\pi\) for the area per se though

Answer 7

hmmm

Answer 8

anyhyow....hmm can you see what the area is?
is really just a shape made from 4 circles in a square, notice the picture
keep in mind the square has a side of 2
thus the diameter of each circle is 2
thus their radius is 1

keep in mind that the area of a circle is \(\bf 2\pi r^2\)

so, first off, subtract 2 semi-circles from the square, that is 2 semi-circles = 1 full circle

that'd leave the two triangular shapes area
divided by 2, would give one of them

and if you subtract that from a semi-circle.... that leaves you with the shaded area

Answer 9

hmmm shoot forgot to add the picture..dohhh anyhow

Answer 10

hmmm area of a circle is \(\bf \pi r^2\) rather =)

Answer 11

and then notice that those two shapes left-over after the substraction, are the same ones as the traverse one
