How do you find the circumferences of 10ft?
First you times 3.14 by the diameter and there you go
What is the ratio of the circumferences of two wheels if the ratio of their radii is 2 to 3?
The ratio of all lengths is the same. The ratio of the circumferences = ratio of the radii = 2:3
What are the circumferences of the planets?
It is the planet's diameter multiplied by pi
If the diameter of a circle is 30Cm What is the circumferences?
d = 9.55 cm
What is the ratio of the circumferences radii and areas of two circles with circumferences of π and 4π?
Ratio of circumference is π : 4π = 1 : 4 This is the ratio of all lengths, therefore their radii are in the ratio of 1:4 also. Ratio of areas is the square of the ratio of length → ratio of their areas is 1² : 4² = 1 : 16
Calculate the circumference of a circle with each diameter?
Multiply each of the diameters by pi (pi = 3.14159265 or 3.14 for rough approximation) to find the circumferences of the circles.
The diameter of a car tire is 40cm and the diameter of a toy car tire is 18mm. Find the ratio of the diameter of the car to the diameter of the toy car?
The diameter of a car tire is 40cm and the diameter of a toy car tire is 18mm. Find the ratio of the diameter of the car to the diameter of the toy car
If the areas of two circles are 48 and 75 find the ratio of their circumferences?
48 works out as a circumference of 24.5597207 units 75 works out as a circumference of 30.69980124 units So the ratio is about 4:5
How do you find the circumferences in a circle?
If you are given the radius (r) or diameter (d, which is twice the length of the radius) the equation to find the circumference (C) is: C=d(pi) or C=2r(pi).
If a circle has the diameter of 14 inches then what is its circumferences?
14 pi inches = a whisker under 44 inches
What is the ratio of the circumferences for two circles with areas 6 pi m2 and 150 pi m2?
area = 2pi*r2circumference = 2pi*rThe ratio of their circumferences will be 2pi*r1 /2pi*r2 = r1/r21) r2 = 6pi/2pi = 3. r1 = root(3).2) r = 150pi/2pi = 75. r2 = root(75)So the ratio of their circumferences isr1/r2 = root(3)/root(75)
Find the ratio of the circumference to the diameter for each circle 3?
For any circle in a plane, the ratio of circumference to diameter is a number called pi, approximately 3.14.
