Answer:
Possible dimensions are and
Step-by-step explanation:
Given:
Volume of a cylinder is
To find: Dimensions of a cylinder
Solution:
Let denote height of a cylinder.
Volume of a cylinder =
Therefore,
One possible dimension can be .
Also, can be written as
So, another possible dimension can be
The ice cream cone consists of a semi-circle with a diameter of 10 cm and a triangle with a base of 10 cm and height of 12 cm.
The area of a semi-circle is half the area of a full circle, so we can find it by using:
If the diameter of the circle is 10 cm, then the radius is 5 cm. Plug in the known values:
or about 39.25
The area of a triangle is:
So we can plug in the known values to find the area to be:
When we add the areas of the two sections together, we get an exact answer of:
(60 + 12.5pi) cm^2
or about
99.25 cm^2
