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.
The circumference of a circle is its diameter times pi, which is the same as twice the radius times pi.A = 2r (pi)In this instance, the circumference is 32(pi) inches(about 100.53 inches)
9.628874057 square inches rounded to two decimal places is 9.63 square inches.
No, you add up all the sides. Yes, in terms of a circle. To determine the perimeter or circumference of a circle, you must multiply: 2πr or two times Pi times the radius of the circle.
Pi times the diameter.
"In terms of pi" means that if your doing volume of a sphere the answer you get by using the formula (4 over 3) times pi radius cubed and get your answer with pi and your unit cubed after it. Then you simply multiply by pi to get "in terms of pi."------------------------------------This phrase occurs when doing calculations which require π, eg circumference or area of a circle.It means do not use some value for π (eg 22/7, 3.14, 3.14159) but leave π in the answer.eg find the circumference of a circle with a radius of 5 cm in terms of πcircumference = 2 × π × radius = 2 × π × 5 cm = 10π cmBy leaving it in terms of π it is an exact answer; the same example could have been written:find the exact circumference of a circle with a radius of 5 cmIn which case the answer would be 10π cm
Circumference = 2*pi*radius = 26*pi inches
36*pi inches
Circumference = 2*pi*r = 34*pi inches.
The circumference of a circle is its diameter times pi, which is the same as twice the radius times pi.A = 2r (pi)In this instance, the circumference is 32(pi) inches(about 100.53 inches)
find the radius of a circle with circumference of 42.1
Area Diameter Radius Circumference
The circumference C = 2 r times pi C = 76 inches times pi. pi = 3.141592654...
Circumference = 2*pi*radius or pi*diameter Circumference = 36pi inches
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.
As pi is the ratio of the ratio of the circumference (C) of any circle to its diameter (d), the circumference of a circle in terms of pi is: C = pi x d The circumference of a circle is pi times its diameter or 2 pi times its radius (since a diameter is 2 times the radius).
pi = circumference/diameter circumference = pi*diameter or 2*pi*radius
The formula for finding the circumference is the diameter times pi because the radius is half of the diameter, the diameter of this circle would be 8 8 times pi equals approximately 25.1327 Or you could leave it in terms of pi and say 8pi (using the symbol)
