Given:
Radius of the cone = 6
Slant height of the cone = 10
To find:
The lateral area, surface area and volume of the cone.
Solution:
Let h be the height of the cone. By Pythagoras theorem, we get
Taking square root on both sides, we get
The lateral area of a cone is:
The surface area of a cone is:
Volume of cone is:
Therefore, the lateral area of a cone is sq. units, the surface area of a cone is
sq. units and the volume of the cone is
cubic units.
Answer:
K-a Positive constant that depends on the area and nature of the surface of the body under consideration.
Step-by-step explanation:
Newtons law cooling describes the rate at which an exposed body changes temperature through radiation which is approximately proportional to the difference between the object’s temperature and its surroundings, provided the difference is small. The formula is given as:
where,T- temperature at time t, is temperature of the surrounding and k- A Positive constant that depends on the area and nature of the surface of the body under consideration.
