Question

What is the approximate area of the shaded region?

Answer 1

You have to find the area of the square and the area of the circle. Let's do the circle first. A circle's area formula is \[\Pi r ^{2}\]The figure only gives us the diameter of the circle. SO we have to divide 7 by 2. What do you get when you do that?

Answer 2

Plug in the quotient then solve.

Answer 3

I'm like really confused

Answer 4

well, 7/2 is 3.5

Answer 5

Ok. The question asks for the area of the shaded region. That's this part.

To find that area of the shaded region, we have to find the area of the whole square.

And the area of the circle. Let's find the area of the circle first. You just divided 7 by 2. 3.5 is right. The area formula of a circle is \[\Pi r ^{2}\]Pi is 3.14 and the r is the radius. You just found the radius which is 3.5 \[3.14\times3.5^{2}\]Or you can do this.\[3.14\times3.5\times3.5\]

Answer 6

What do you get when you multiply those?

Answer 7

Answer 8

38.465?

Answer 9

Yep. Remember that number. Now we need to find the area of the whole square. You just have to multiply \[7\times7\]Because the area formula of a square is \[Length \times Width\]What do you get when you multiply that?

Answer 10

49

Answer 11

Right. Now we can subtract the areas to find what the area of the shaded region is. \[49-38.465\]

Answer 12

What do you get when you subtract those? You get your answer once you do that?

Answer 13

*that.

Answer 14

10.535?

Answer 15

Yep, that's the answer.
