What is the area of a circle in terms of its circumference?
Using the circumference, you would find the radius first. The circumference C = 2*Pi*r where r is the radius. Then, the area of the circle = Pi*r^2.
If circle A has a radius of 3 cm and circle B has a radius of 4 cm and circle C has the same total area as circles A and B combined hoe do you determine the radius of circle C?
The formual for area is: A = πr2 so the area of circle A (assuming π=3.142) is 28.278cm2, and the area of circle B is 50.272cm2.Their combined area of 78.55cm2 is the area of circle C.The formula for radius is: square root of A/π78.55 ÷ 3.142 = 25, the square root of 25 is 5The radius of circle C is 5cmArea of Circle A = π32 = 9πArea of Circle B = π42 = 16πArea of Circle C = 9π + 16π = 25πLet r = radius of Circle C thenπr2 = 25π : r2 = 25 : r = 5.
How do you express the area of a circle as a function of its circumference?
By using the well-known formula, A = pi x r2, and expressing the radius in terms of the circumference, r = c / (2 x pi). Replace in the first formula, and simplify. f
What is the area of a 7 cm c cercle?
Area of a circle = pi*radius2
Find the dimensions of the rectangle of largest area that can be inscribed in a circle of radius a in C programming?
Find the dimensions of the rectangle of largest area that can be inscribed in a circle of radius a in C programming
How do you express the area of a circle as a function of its radius?
If a circle has radius r, then the area of the circle is pi r2, pi being about 3.14159. I beleive the function you are looking for is A(c)=c/2*r
Can you develop a formula for the circumference of a circle as a function of its area?
A = π(r)² √(A/π)=r C = 2π(r) C = 2π(√(A/π)) ■

How do you find an area of a shape rectangle square and a circle in C program?
By using that one thing.
What is the area of a circle with a radius of 4mm use 3.14 for pi?
Using 3.14 as Pi the area of circle is: 50.24
If the area of a circle is 201.06 then the circumference of the circle is?
The formula to find the circumference of a circle is C = 2πr, where r is the radius of the circle. To find the circumference, you first need to find the radius by using the formula for the area of a circle (A = πr^2). Given that the area is 201.06, you can solve for the radius. Once you have the radius, you can plug it into the formula C = 2πr to find the circumference.
What are the formulas for circumference and area of circles?
The circumference ( C ) of a circle is calculated using the formula ( C = 2\pi r ), where ( r ) is the radius of the circle. The area ( A ) of a circle is given by the formula ( A = \pi r^2 ). In both formulas, ( \pi ) (pi) is a constant approximately equal to 3.14159.
Program to find area of circle using class in c?
class area{ int l,w,a; a=i*w; printf"area of rectangle is= %d",a; endl; }
What is the area of a circle in terms of its circumference?
Using the circumference, you would find the radius first. The circumference C = 2*Pi*r where r is the radius. Then, the area of the circle = Pi*r^2.
What is the c plus plus program to calculate the area of a circle using function overloading?
Function overloading is used when you want to re-use the same function name with different argument types or a different number of arguments. Calculating the area of a circle isn't the sort of function that requires overloading since the only argument you need is the radius. double area_of_circle (const double radius) { const double pi=4*atan(1); return pi*radius*radius; }
What is the formula of area in circumference?
The area of a circle is calculated using the formula ( A = \pi r^2 ), where ( A ) is the area and ( r ) is the radius of the circle. The circumference of a circle, which is the distance around it, is given by the formula ( C = 2\pi r ). While the area formula focuses on the space within the circle, the circumference measures its outer boundary.
How can you express area and circumference of a circle in terms of pie?
The area ( A ) of a circle can be expressed in terms of pi (( \pi )) using the formula ( A = \pi r^2 ), where ( r ) is the radius of the circle. The circumference ( C ) of a circle is given by the formula ( C = 2\pi r ). Both formulas highlight the fundamental role of ( \pi ) in relating the dimensions of a circle to its geometric properties.
