What is the circumference of radius equals 90 FT?
C = pi*r82 C = Pi*r*2 90=R Thus 180*Pi
What is the radius If the circumference is 96.5?
C = pi times 2 radius or radius = C / (pi times 2) = 96.5 / (3.14 times 2) = 96.5 / 6.28 = 15.37
What does c equals 2nr mean?
The circumference of a circle is: 2*pi*radius
What is the circumference of radius equals 3.5 cm?
C=2 pi r C = 2 * 3.14 * 3.5 cm C= 21.98 cm
The radius of a circle is 5 inches What is the circumference of the circle?
Circumference is 2 times pi times radius, so the circumference of this circle is 2 times pi times 5, or 10 times pi. If a decimal answer is needed, pi is approximately 3.14, so C=31.4
Is circumference radius times pi?
NO!!!! C = 2 pi r C = pi d In words ; Circumference equals two times 'pi' times radius or , circumference equals 'pi' times diameter. NB The diameter is twice the radius. Also A = pi r^(2) In words, Area equals 'pi' times the radius squared. Read learn and comit to memory these two circle equations.
What are the two formulas for circumference?
C= 2 times pi and C= pi times diameter C= 2 times pi and C= pi times diameter
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)
What is the length of the radius if the circumference equals 18x3.14 for pie?
9. Circumference equals 2 times Pi times the radius. C=2(pi)r. "r" for radius. So if your circumference is 18 times pi, then you do 18 divided by 2, which gives you a radius of 9.
What fraction of a circumference equals the radius?
2r(pi)=C where C is circumference. Therefore the radius equals C/2(pi)
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.
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 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 radius equals 90 FT?
C = pi*r82 C = Pi*r*2 90=R Thus 180*Pi
What is the radius If the circumference is 96.5?
C = pi times 2 radius or radius = C / (pi times 2) = 96.5 / (3.14 times 2) = 96.5 / 6.28 = 15.37
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.
