What is the circumference of a circle that has a radius of 38 inches in terms of pi?
The circumference C = 2 r times pi C = 76 inches times pi. pi = 3.141592654...
How do you express the area of a circle in terms of diameter?
Circle area = pi*r 2 r= D/2 Circle area = pi*(D/2) 2 = (pi/4)*D 2
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 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 formula that relates circumference and radius?
Read , learn and inwardly digest these two circle eq;n.s C = 2 pi r or C = pi d & A = pi r^(2) Very important when learning circular calculations. Taking the first eq;n C = 2 X pi X r Where C = circumference 2 is a constant pi = 3.141592... ~=~ 3.14 r = radius. NB The three terms on the RHS are MULTIPLIED TOGETHER>
How do you put something in terms of pi?
To express a quantity in terms of pi, you need to relate it to a circular measurement, such as the circumference or area of a circle. For example, if you have the circumference of a circle, you can use the formula ( C = 2\pi r ), where ( r ) is the radius, to express the circumference as a multiple of pi. Similarly, for the area, use ( A = \pi r^2 ) to express the area in terms of pi. Simply factor out pi from the equation to achieve the desired expression.
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.
What is the circumference of circle P express your answer in terms of pi. pa 3?
To find the circumference of circle P, you use the formula ( C = 2\pi r ), where ( r ) is the radius of the circle. If the radius of circle P is given as ( r ), then the circumference can be expressed as ( C = 2\pi r ). If you have a specific radius value, you can substitute it into this formula to get the numerical circumference in terms of pi.
What is the circumference of a circle that has a radius of 38 inches in terms of pi?
The circumference C = 2 r times pi C = 76 inches times pi. pi = 3.141592654...
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
How do you express the area of a circle in terms of diameter?
Circle area = pi*r 2 r= D/2 Circle area = pi*(D/2) 2 = (pi/4)*D 2
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
How do you write the circumference of the circle in terms of pi?
The circumference of a circle can be expressed in terms of pi using the formula ( C = 2\pi r ), where ( C ) represents the circumference and ( r ) is the radius of the circle. Alternatively, if the diameter ( d ) is known, it can also be written as ( C = \pi d ). This shows that the circumference is directly proportional to both the radius and diameter of the circle.
What is the circumference of a circle with a radius 5x plus 1 in terms of x?
C = pi*2r, where C is the circumference and r is the radius.In this case, C = pi*2(5x+1), which can also be written as to C = pi*(10x+2).
What is the circumference of a 12 inch round circle in pi?
Assuming the '12 inch' is the radius. Then C = 2 pi r C = 2 pi 12 C = 24 pi ( Thr asnswer in terms of 'pi').
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 radius of a circle with circumference of 8 inches?
