Answer:
D.Dilate circle A by a scale factor of 5.
Step-by-step explanation:
We are given that
The center of circle A is (2,8) and radius of circle A is 2.
The center of circle B is (5,4) and radius of circle B is 10.
We have to find the steps will help to show that circle A is similar to circle B.
When two circles are similar it means the size of circles can be same or different.Therefore, radius of circles will be same or different.
But, the radius of circles are different.
Dilation: It is a transformation in which obtained figure is similar to the original figure.
Shape remains same but the size of figures are different.
Ratio of corresponding sides of two figures=Scale factor
When a circle is dilated then,
Ratio of radius of circle obtained after dilation to the radius of original circle= Scale factor
Scale factor=
Hence, option D is true.
Answer:
The Volume of large cone is 19.545 greater than the smaller cone
Step-by-step explanation:
Given:
Size of the small cone = 3.5 inches
Diameter of the small cone = 3 inches
Size of the large cone = 3.5 inches
Diameter of the small cone = 3 inches
To Find:
How much greater, to the nearest tenth of a cubic inch, is the volume of the larger cone than the volume of the smaller cone = ?
Solution:
Volume of the small cone :
Radius =
Radius =
Radius = 1.5 inches
volume of the cone =
substituting the values,
=>
=>
=> 16.485
Volume of the large cone :
Volume of the large cone :
Radius =
Radius =
Radius = 2.25 inches
volume of the cone =
substituting the values,
=>
=>
=>36.06
Now ,
volume of small cone - volume of large cone
=>36.06 - 16.485
=>19.545
