Well, isn't that just a happy little math question! To express r in terms of c and pi, you can use the formula for the circumference of a circle: c = 2 * pi * r. To solve for r, you simply divide both sides by 2pi, giving you r = c / (2 * pi). Just like painting a beautiful landscape, sometimes all it takes is a few simple brushstrokes to reveal the true beauty within!
Well, honey, expressing "r" in terms of "c" and "pi" is as easy as pie! Just divide "c" by 2pi, and there you have it - r = c / (2pi). It's as simple as that, darling.

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 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?

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 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?
C = 2*pi*r 8 = 2*pi*r 4 = pi*r r = 4/pi
The can has a volume of 342 cm3 and a diameter of 6 cm express the height in terms of pi?
v = pi*r^2*h 342 = pi * 3^2 * h 342 = 9h*pi 38 = pi*h h = 38 / pi
How do you find the radius of a circle if all you know is the circumference?
C = circumference r = radius C = 2 x pi x r C / 2 = pi x r C / 2 / pi = r
What is the circumference of a circle with a radius of 56 inches in terms of pi?
The formula for the circumference of a circle is C = pi r2 where r is the radius. Substituting 56 inches for the radius gives: C = pi(56)2 = (3136)pi inches.
What is the formula that relates circumference and radius?

A circle has a circumference of 16 pi inches what is its radius?
The formula where C=circumference, R=radius is C = 2 pi R Since C = 16 pi inches and 16 pi = 2 pi R we can solve for R and get R= 16 pi /2 pi = 8 Therefore the Radius is 8 inches.
