Answer:
13 cm is the height of the cone
The vertical height = 12 , the radius = 1/2 * 10 = 5, so:
s^2 = 5^2 + 12^2 where s is the slant height.
x^2 169
s = 13 cm (answer).
is the height of the cone
Step-by-step explanation:
Since the base of a cone is a circle, we substitute 2πr for p and πr2 for B where r is the radius of the base of the cylinder. So, the formula for the lateral surface area of a right cone is L. S. A=πrl , where l is the slant height of the cone .
I will give you an example try to understand it
Example) Find the volume of the cone shown. Round to the nearest tenth of a cubic centimeter.
Solution
From the figure, the radius of the cone is 8 cm and the height is 18 cm.
The formula for the volume of a cone is,
V=13πr2h
Substitute 8 for r and 18 for h .
V=13π(8)2(18)
Simplify.
V=13π(64)(18)=384π≈1206.4
Therefore, the volume of the cone is about 1206.4 cubic centimeters.
Note: this is just an example it is not really the answer hope this helps :)
