Question

The image is below please help

Answer 1

9.4247775 un^2 (you can round it to 9.4; 9.42; or 9.425)

Explanation:

First, you want to find the area of the circle if it was whole.

You can use the equation: A=πr^2

r=2

So, A=π(2)^2 < (and you solve for a)

≈12.56637

The part of the circle which is removed has a 90 degree angle indicating that 1/4 of the circle is cut from the whole and 3/4 is left.

So, we need to find 3/4 of our whole.

3/4(12.56637) = 9.4247775

Answer 2

The shape has 90 degrees missing, as indicated by the image. We need to find the fraction of the shape that is present, and find the area of that.

360 - 90 = 270

270 / 360 = 3/4

Formula for the area of a circle: A = pi x r^2

The radius given is 2 units for this circle. We'll first find the area of the whole circle, then multiply that value by 3/4 to find the area of the shape.

A = pi x 2^2

A = 3.14 x 4

A = 12.56

12.56 x (3/4) = 9.42

A = 9.42 units^2

Hope this helps!! :)
