Not sure of your question since you already have the values for both equations, so I assume you want to calculate what the diameter is. If this is so, you can use the formula for finding circumference to calculate the diameter:
c = pi*d (next substitute with the given values)
87.92 = 3.014*d (next divide both sides by 3.14 to find the diameter)
28 = d
28 this is the diameter of a circle that has a circumference of 87.92

What does circumference equals pi times d mean?
It is the formula for the circumference C of a circle where D is the diameter. C = (pi) D
What is the circumference of a circle with a diameter of 84?
Circumference equals pi times diameter; so C = 84*pi or about 263.9.
If the area of a circle is 314 square inches what is the circumference of the circle?
62.8 inches. the formula for a circle's area is a = pi x r squared. substitute 3.14 for pi and 314 for a. 314 = 3.14 x r squared (divide both sides by 3.14) v 100 = r squared (find the square root of both sides) v r = positive or negative 10 . since it stands for the radius of a circle, it has to be positive. now that you know the circle's radius, you can solve the circumference formula, c = 2 x pi x r. c = 2 x 3.14 x 10 c = 62.8
What is the circumference of circle with 40 foot diameter?
By definition pi is the ratio between the circumference and the diameter pi=C/D so C=pi*D and C=pi*40=125.6 (if pi=3.14)
What is the formula for circumfrence?
Circumference of a circle = 2*pi*radius or pi*diameter
What fraction of a circumference equals the radius?
2r(pi)=C where C is circumference. Therefore the radius equals C/2(pi)
What is the period of the function f of x equals cos2x a. 1 half b. pi divided by 2 c. pi d. 2?
the answer is c, pi
Is c equals 2πr the same as c equals πr squared?
No. C = 2*pi*r is the equation representing the circumference of a circle. The area of a circle is equal to pi*(r^2).
What is the circumference of radius equals 90 FT?
C = pi*r82 C = Pi*r*2 90=R Thus 180*Pi
What does circumference equals pi times d mean?
It is the formula for the circumference C of a circle where D is the diameter. C = (pi) D
What is the circumference of r equals 3.20?
C=2(pi)(r) therefore if r equals 3.20 then C=20.1061929
Circumference of a circle 22 inches in diameter?
C=pi*dcircumference equals pi times diameter.Which means 3.14 (which we will use for pi) times 22 equals 69.08 in.
C equals 3.1416 times 10?
In that case, C = 31.416So in a circle circumference (C) = pi * diameter. So 3.1416 is an approximation of pi, and the diameter is 10.
Could someone help with a math question C equals 9.42ft D equals blank Can you tell me how to find the diameter?
Circumference = pi*Diameter So D = C/pi = 9.42/3.14 (using a crude approximation for pi) and that is equal to 3.
What is the equation to get circumference of a circle if you have diameter?
Circumference = Pi x Diameter (Pi equals 3.14)
C equals 2pei R find for R?
Presumably C means circumference and R means radius? If C = 2*pi*R Then R = C divided by 2*pi
If the radius equals 2cm what is the circumference?
C = 2 * (pi) * (radius) So plug in 2 for radius C = 2 * (pi) * (2) C= 4(pi) If you need to approximate multiply 4 times 3.14. If you do not need to approximate then your answer is 4(pi)
