Your answer to this question Plateau
Answer:
A. 3
Explanation:
A cone is a three dimensional shape with a flat base and curved surface. A right circular cone is a cone where the axis of the cone is the line meeting the vertex to the midpoint of the circular base.
The volume of a right circular cone = πr²h/3; where r is the radius of the cone and h is the height of the cone.
Let us assume the cone has a height of h, and radius of r. Hence:
Volume (V₁) = πr²h/3
If the radius remains fixed and the height is multiplied by 3. Hence:
V₂ = πr²(3h)/3 = πr²h = 3V₁
The volume would be multiplied by 3
Answer:
Conventional sources of energy is also called non-renewable sources of energy while non conventional sources of energy is called renewable sources of energy.
An example of conventional energy is coal, crude oil and natural gas. The advantage is the availability and affordability. The disadvantage is the level of air pollutants such as CO2 and CO it releases to the atmosphere which is harmful as it poses a risk of air borne illnesses.
An example of non conventional energy is the sun, wind , water etc. The advantage is that it reduces the risk of air pollution and keeps the environment clean as no toxic substances are being released into the atmosphere when used. The disadvantage is they are expensive and aren’t available all year round.
