The area of the pier is approximately 1231.62 square meters.

A circle is a two-dimensional figure with a radius and circumference of 2pir.

The area of a circle is πr².

We have,

The pier is in the shape of a semicircle.

So,

The area of a semicircle is half of the area of a circle with the same diameter.

The area of a circle with a diameter of 56m is:

A = πr² = π(28)² = 2463.23 m²

So,

The area of the semicircle is:

A/2 = 2463.23/2= 1231.62 m²

Therefore,

The area of the pier is approximately 1231.62 square meters.

Answer:

Step-by-step explanation:

Answer:

A rectangle

Step-by-step explanation:

The given parameters are;

The quadrilateral ABCD is a rhombus;

The length of the sides of the rhombus = 12 inches

The lengths of the sides of a rhombus are equal

The opposite interior angles of the rhombus are equal

The length of each midpoint from the vertex = 12 in./2  = 6 in.

Therefore, we have;

The line joining the midpoints form a quadrilateral with the length of the opposite sides equal

The sum of the interior angles of the rhombus = 180°

From the diagram created with Microsoft Visio, we have;

4·a + 4·b + 360 = 4 × 180 = 360 + 360

4·a + 4·b = 360

a + b = 90°

We have;

The interior angles of the quadrilateral formed = x

a + b + x = 180° Sum of angles on a straight line

∴ x = 180° - (a + b) = 180° - 90° = 90°

x = 90°

Therefore, the interior angles of the quadrilateral formed = 90°

The quadrilateral formed having equal opposite sides, and all interior angle of 90° each is a rectangle

Answer:

b = 37 degrees

Step-by-step explanation:

all of the angles on a triangle added up equal 180 degrees

111 degrees

32 degrees

111 + 32 = 143

180 - 143 = 37

b angle = 37 degrees

Answer: 37 degrees.

Step-by-step explanation: a triangles degrees all add up to 180 so 111+32=143 and 180-143=37 so 37 degrees.

Answer:

the slope of the line that lies on those two points is 11/7

Step-by-step explanation:

insert the first point into y=mx+b

14=(-7)m+b

----------------

Do it again with the other point

3=(-14)m+b

-------------

Now put both equations in a system of equations

14=(-7)m+b

3=(-14)m+b

solve for m and b

m=11/7 and b=25

y=11/7x+25

m=slope

b=y-intercept

Answer:

P = 4/7

Step-by-step explanation:

There are 5 cards with a picture of a rose and 3 cards with a picture of a daisy.

Then we have a total of 8 cards.

Now Alia turns over one card, and this card has a picture of a rose, then she removes it.

This means that now there are 4 cards with a picture of a rose and 3 cards with a picture of a daisy, so now we have a total of 7 cards.

We want to find the probability that the next turned card has also a rose on it.

This will be equal to the quotient between the number of cards with a rose on it (4 cards) and the total number of cards (7)

Then the probability is:

P = 4/7
