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 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)
What is the ratio for the volumes of two similar spheres given that the ratio of their radii is 3 4?
ratio of volumes is the cube of the ratio of lengths radii (lengths) in ratio 3 : 4 → volume in ratio 3³ : 4³ = 27 : 64
What will be the ratio of circles to triangles in a drawing showing 4 circles and 7 triangles?
4/(7) = 4/7 is the ratio of circles to triangles. Some prefer to express this as 4:7.
If the ratio between the radii of the two spheres is 3 to 5 what is the ratio of their volumes?
3^3 / 5^3 = 27 / 125
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
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
The circumference of Circle K is π The circumference of Circle L is 4 π. What is the ratio of their circumferences of their radii of ther areas?
The circumference of Circle K is ( \pi ), which implies its radius ( r_K ) is ( \frac{1}{2} ). For Circle L, with a circumference of ( 4\pi ), its radius ( r_L ) is ( 2 ). The ratio of their radii is ( \frac{r_K}{r_L} = \frac{1/2}{2} = \frac{1}{4} ). The areas of the circles are proportional to the squares of their radii, so the ratio of their areas is ( \frac{(r_K)^2}{(r_L)^2} = \frac{(1/2)^2}{(2)^2} = \frac{1/4}{4} = \frac{1}{16} ).
What is the relationship between area of a circle and its radius squared for a series of circles with large increasingly large radii?
The area of a circle is directly proportional to the square of its radius. If two circles have radii R1 and R2 , then the ratio of their areas is ( R1/R2 )2
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)
What factor of both the wheel and the axel can be use to calculate their mechanical advantage?
Their radii, diameters or circumferences - in all three cases the ratio between the axle and wheel are the same.
What is the ratio of 2 circles and 3 triangles?
The ratio of two circles to three triangles is not a straightforward comparison as circles and triangles are different shapes. However, if we are comparing the areas of two circles to the combined areas of three triangles, we would need to calculate the area of each shape using their respective formulas (πr^2 for circles and 1/2 base x height for triangles) and then compare the total areas. The ratio would then be the total area of the circles divided by the total area of the triangles.
How do you make transverse common tangent to two circles?
You join the centres of the two circles. Divide this line in the ratio of the two radii. Draw the tangent from this point to either circle and extend it to touch the other circle.
How do you find the ratio between two circles when the diameters are given?
If you mean ratio then I don't quite understand the question.. but if you mean RADIUS Then you take the diameter and divide it by two. ============================================== There's no such thing as the ratio of circles. You can find the ratio of their diameters, the ratio of their radiussesses, and the ratio of their areas. -- The ratio of their diameters is: One diameter divided by the other one. -- The ratio of their radiusses is the same number as the ratio of their diameters. -- The ratio of their areas is the square of that same number.
What is the ratio for the volumes of two similar spheres given that the ratio of their radii is 3 4?
ratio of volumes is the cube of the ratio of lengths radii (lengths) in ratio 3 : 4 → volume in ratio 3³ : 4³ = 27 : 64
What is the relation between angular velocities of a pair of coupled gears of different radii?
The angular velocities of a pair of coupled gears are inversely proportional to their radii. This means that the gear with a larger radius will rotate more slowly than the gear with a smaller radius. The ratio of their angular velocities is equal to the ratio of their radii.
Are all cylinders with the same radii similar?
No. To be similar ALL lengths must be in the same ratio. If two cylinders have the same radii, but different heights then the radii have one ratio (1:1) but the heights have a different ratio; thus they are not similar.
