Answer:
The center is of the whole target.
Step-by-step explanation:
Given:
Diameter of the center = 5 inches
Diameter of the whole target = 25 inches
We need to find the part of the center to the whole target.
Solution,
Firstly we will find out the areas of center and whole target.
For center;
Diameter = 5 in
Radius of circle is equal to half of the diameter.
radius =
Now we know that the area of circle is equal to π times square of the radius.
framing in equation form, we get;
Area =
For whole target;
Diameter = 25 in
Radius of circle is equal to half of the diameter.
radius =
Now we know that the area of circle is equal to π times square of the radius.
framing in equation form, we get;
Area =
Now to find the part of the center to the whole target we will divide Area of center with Area of the target.
framing in equation form we get;
the part of the center to the whole target =
Hence the center is of the whole target.
Answer: A cone with height 3 and radius 1
Step-by-step explanation:
Hi, searching I found the image for the question, attached down below.
By rotating the triangle about line m, a cone with height 3 and radius 1 is produced.
Solid 3d objects are produced by rotating a 2d figure around a straight line that lies in the same place.
in our case, if we rotate the triangle around the line, the vertices in touch with the line m remains stationary, while the remaining vertex follows the path of a circle, creating a cone.
