### A dog is on a 10 foot leash in the backyard. how much area does the dog have to run.round to the nearest hundreth.use 3.14 for pi

The area of a circle is pi * r squared. Given the stake is in the middle that is the R so 3.14 * 10 * 10 or 3.14 * 100 = 314

### Area of circle

(pi)R squared (Fixya won't let me use the sign for Pi)

example: suppose the radius of a circle is 10 inches, then the Area of the circle would be pi times 10 times 10 or 100*pi

pi represents the circumference (distance around) of a circle / diameter and for any circle is constantly the same number which is approximately 3.14

so in my example 100*pi=100*3.14 or 314 square inches

### / The diagram shows corresponding lengths in two similar figures. Find the area of the smaller figure. A. 16 cm2 B. 18 cm2 C. 20 cm2 D. 36 cm2

Your question is not clear at all. What are all those area measures in cm^2?
Take two segments that correspond to one another and for which you have the lengths.
This will allow you to find the scale factor k.
k= (length of a segment in smaller figure)/(length of the corresponding segment in larger figure).
Then
Area of smaller figure =k^2(area of larger figure)
In the formula above insert the area of the larger figure as given to you or as calculated by you using the shape and dimensions of the figure.

### Help finding the circumferance of a circle

The circumference of a circle is given by the expression
Circumference= 2* PI* Radius of circle
C=2*Pi*R
The area is given by
Area of a disk with radius R = Pi* R*R or PI*R^2
Area= PI*R^2

### How would you represent the area of the base of the box?

Total Surface Area

The total surface area is made up of three pairs of sides for a total of six sides.

We must find Areahw, which is the area of the side that is h by w.

Areahw = (h)(w)

We must find Areahl, which is the area of the side that is h by l.

Areahl = (h)(l)

We must find Areawl, which is the area of the side that is w by l.

Areawl = (w)(l)

Each of the above areas are present on two sides of the box. So, the total surface area is sum of twice each of these areas, that is:

Total Surface Area = 2(Areahw) + 2(Areahl) + 2(Areawl)

Example:

Let h = 3 cm, w = 5 cm, l = 8 cm

Areahw = (h)(w) = (3 cm)(5 cm) = 15 cm2
Areahl = (h)(l) = (3 cm)(8 cm) = 24 cm2
Areawl = (w)(l) = (5 cm)(8 cm) = 40 cm2

Total Surface Area = 2(Areahw) + 2(Areahl) + 2(Areawl)
Total Surface Area = 2(15 cm2) + 2(24 cm2) + 2(40 cm2)
Total Surface Area = 30 cm2 + 48 cm2 + 80 cm2
Total Surface Area = 158 cm2

### A pizza is divided into 8 equal parts. what is the area of one slice if its radius is 6 inches?

Hello and Welcome to FixYa!
Area of pizza (Combined Bread + Crust) = Area=pie * (radius)^2. If divided in 8 equal parts, Area of 1 piece=Area/8.
Area= 3.1415* (0.1524)^2 Area of 1 slice= Area/8 Concerned.

### A pool with a radius of 2.5 metres surrounded by a path 0.8 metres wide what is the perimetee of the pool .using the value of 3.142

Hello,
You must have been taught the relation between the circumference (perimeter) of a circle, the radius and pi. Use it to calculate the perimeter. It is true for all circular figure.
Depending on what is really asked (the perimeter of the actual pool where you find the water, or the general pool area where no shoes are allowed)
1st case: use the radius that was given.
2nd case: the total radius is the radius given plus the width of the path.

If you do not have a formula for the perimeter that involves the radius, but have one that involves the diameter you can use it too, knowing that the diameter is twice the radius or the radius is one half of the diameter.

As you might have guessed I was not going to make things too easy for you by providing a ready-made answer, but I gave you all the hints that will help you solve the problem.

### Example of program in c++ and there code

Hello my friend, I am Jonas I work as a programmer in some various programming languages. Here try this code:
This program is design to output the Diameter, circumference, and area given a radius of a circle. #include <iostream.h> int main() { int radius, diameter, circumference, area, pi; cout << " Enter the radius of a circle\n"; cin >> radius; pi = 3.14159; diameter = 2 * radius; circumference = 2 * pi * radius; area = pi * (radius)^2; cout << "Diameter formula executing.....(2 x r)\n"; cout << "Diameter is " << diameter << endl; cout << "circumference formula executing.....(2 x pi x r)\n"; cout << "circumference is " << circumference << endl; cout << "area formula executing......(pi x [r x r])\n"; cout << "area is " << area << endl; return 0; }
Also if you need tutorial you can visit this site Learning C++ .Hope this solution will able to help your problem solved. If you need more assistance just reply to this post or send me a mail at geo_jonas@yahoo.comThank you and Godbless.
