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
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 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)
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
A portion of a circle and its interior bound by an arc and to radii is a?
The area bounded by an arc of circle and two radii is known as a "circular sector"
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
What is the relationship between two circles?
Their circumferences are in direct proportion to their radii. Their areas are in direct proportion to the square of their radii.
Two wheels of different sizes with interlocking teeth along their circumferences?
gear and pinion (pinion being the smaller of the two gear wheels)
If the ratio between the radii of two spheres is 23 then what is the ratio of their volumes?
Volume of a sphere of radius r: V = 4pi/3 x r3 If the ratio of the radii of two spheres is 23,then the ratio of their volumes will be 233 = 1,2167
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.
The ratio between the radii of two spheres is 9 2 What is the ratio of their volumes?
729/8
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 ratio for the volumes of two similar spheres given that the ratio of their radii is 2 7?
It is 8 : 343.
What is the ratio for the volume of two similar spheres given that the ratio of their radii is 5 9?
3/4
What is the ratio for the volumes of two similar spheres given that the ratio of their radii is 27?
If the ratio is 2 : 7 then the volumes are in the ratio 8 : 343.
What is the difference in 35 feet and 20 feet in circle answer in pi?
The answer depends on whether the two measures given are radii or diameters and also whether the differences in question are in their circumferences or areas.
What is the ratio for the volumes of two similar cylinders given that the ratio of their heights and radii is 3 7?
It is 27 : 343.
