Answer:

54.85 un²

Step-by-step explanation:

Calculate the square and the circle and add them together.

$2\pi$ r

radius = 3

$2\pi$ 3

Circumference = $2\pi$ r = 2 × $\pi$ × 3 = 18.84956

18.84956 rounds to 18.85

The circle's area is 18.85 un².

The square is 6 by 6.

6 × 6 = 36

The square's area is 36 un².

18.85 un² + 36 un² = 54.85 un²

Step-by-step explanation:

We know that area of Trapezium =

$\sf{\dfrac{1}{2} \times (Sum \ of \ its \ Diagonals) \times height}$

1/2 * (16+48) * 20

= 640 m²

Now, for semicircle,

1/2 * pi * r²

= 1/2 * 3.14 * 18.86 * 18.86

= 558.44 m²

Adding both,

1198.44 m² ~ 2000 m²

Hope it helps :)

Find the area of the regular polygon 7 in

nata0808 [166]

Ummmm that’s a triangle but I guess I’ll solve for both 7x7= 49/2= 24.5 triangle. Polygon is different but I guess if the perimeter and line to the center is both 7 okay 7x5= 35x7= 245/2= 122.5 cause triangle is wxL /2 and polygon is AxP/2 soooo I hope this helped

Make a ven diagram for a rhombus and a parallelogram

larisa86 [58]

Step-by-step answer:

First we need to know the properties of the given figures.

There are many ways to describe a parallelogram. Here we will use the simple description that

"A parallelogram is a convex quadrilateral with opposite sides equal and parallel."

If we take pencil and paper to construct two parallel and equal lines, and join the corresponding points, we can only get a parallelogram (as long as the figure is convex.

Similarly, if we draw four equal lines to draw a parallelogram, we can only get a rhombus. Therefore a rhombus is a parallelogram with all four sides equal.

See the Venn diagram attached.

Note

(in fact, the minimum definition of a rhombus is "a parallelogram with two adjacent sides equal")
