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:

r = 8 ft

Step-by-step explanation:

Area of a circle => πr²

We are told in the question that:

The area of circle Z is 64Pi ft²

= 64π ft²

What is the value of r

We equate

πr² = 64 π

r² = 64 π/π

r² = 64

We square root both sides.

√r² = √64

r =>8 ft

The radius of the given circle Z is 8ft which was solved using the area of the circle

Data;

The formula of area of a circle is given as

[tex]A = \pi r^2[/tex]

Let's substitute the values and solve

[tex]A = 64\pi\\A = \pi r^2 \\64 \pi = \pi r^2\\[/tex]

divide through by π

[tex]64\pi = \pi r^2\\\\64 = r^2\\[/tex]

Let's take the square root of both sides

[tex]r^2 = 64\\r = \sqrt{64} \\r = 8ft[/tex]

The radius of the circle Z is 8ft

since a,7,b,23,c are in A.P.

first term t1=a

second term t2=7

common difference (d)=7-a

forth term t4=a+3d

23=a+3(7-a)

Answer:

562 $ for nine doors

Step-by-step explanation:

Answer:

First image: (6, -1)

2nd image: y = 63

Explanation:

1)

2x + y = 11

1/2x - 5y = 8

y = -2x + 11

1/2x - 5(-2x + 11) = 8

1/2x + 10x - 55 = 8

10.5x - 55 = 8

10.5x = 63

x = 6

2x + y = 11

2(6) + y = 11

12 + y = 11

y = -1

(x , y) = (6, -1)

2)

1/4(8y - 4.8) = 2 (0.9y + 5.4) + 3/5

2y - 1.2 = 1.8y + 10.8 + 0.6

0.2y - 1.2 = 11.4

0.2y = 12.6

y = 63

Answer:

The answer is 45

Step-by-step explanation:

First, you find what is half of 30 by dividing 30 by 2

30/2 = 15

Then you add 15 to 30 since you have to increase it by 1/2

30 + 15 = 45

A person can order a meal in 60 different ways.

Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

We are given that a lunch menu has 3 sandwhiches, 4 types of chips, and 5 types of drinks.

Here we will use the combination of the data.

To answer this we just need to multiply 3 x 4 x 5.

3 x 4 x 5 =  60

Therefore, 60 ways can a person order a meal.
