Find the area of this shape
Stolb23 [73]

Answer:

171.06 cm²

Step-by-step explanation:

<u>First let us find the area of the circle</u>

Area = π r²

        =  π × 8 × 8

        =  π × 64

        = 201.06 cm²

<u>Now let us find the area of parallelogram</u>

Area = Base × Height

        = 6 cm × 5 cm

        = 30 cm²

<u>And now we have to find the area of the shape when the parallelogram is cut from it</u>

<em>For that, you have to subtract the area of the parallelogram from the area of the circle.</em>

Let us solve now.

Area of the shape = Area of the circle - Area of the parallelogram

                               =  201.06 cm² - 30 cm²

                               =  171.06 cm²

Answer:

Length: 12

Width: 2\sqrt{10\\}

Area: 24\sqrt{10\\}

Step-by-step explanation:

We first find the points of C and D to find the length.

C: (-4,-5)

D: (2,-3)

The distance is 2\sqrt{10\\.

Now for the height.

A: (2,9)

D: (2,-3)

The distance is 12.

Area: 2\sqrt{10\\×12 = 24\sqrt{10\\}
