Exponential Functions in the center of a circle 9ft. in radius is a frog. it begins to jump in a straight line to the circumference of the circle. its first jump 4 ft. 6in., its second 2ft.3 in., and it continues to jump haft length of the preceeding jump. how many jumps does the frog make to get out of the circle? How can i do this exponential function for simple process?

If you would like to know the circumference of a 15" diameter circle this is the formula:
circumference = radius x 2 x pi
circumference = diameter x pi
in our case:
circumference = 15" x 3,14
circumference = 47 ,1" (that's 119,634 cm)
What do you mean? The circumference of a circle having a radius or 15"? If so, it will be [2 x 3.14 x 15] = 94.2".
Since circumference of a circle = 2 x (pai) x r (r = radius) Gopakumar Gopalan Google
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
If you know the center, measure the distance between the center and one point on the circumference. Measure with the opening of a compass and report on a ruler, or use a ruler.
Take the measure of the radius and multiply by 2. Any other indirect way of getting the radius does not constitute a measure but a calculation.
The diameter of a circle enters in two formulas.
Length of Circumference: C=Pi*D (D diameter) ====>D=C/Pi
Area of the disk A=Pi *D^2/4 =====>D=SQRT(4*A/Pi), SQRT is the square root operation.
To get a circle with a perimeter of 18 inches, you want a diameter of about 5.73 inches (just under 5 3/4 inches) or a radius of 2.86 inches (call it 2 7/8 inches). Get a compass, set its legs 2 and 7/8 inches apart, put one end at the center, and turn.
The radius and the coordinates of the center will completely define a circle. Some other measurements include the diameter, circumference, and area. Then there are parts of the circle, such as arc and chord.
what class are you in? Is this your home work?
Anyway, You should know that
Circumference = 2 x pie x radius
therefore radius - circumference / 2 x pie
in this case
radius = 30 x 7 / 2 x 22
= 210 / 44
Now you can calculate that fraction.
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;
