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
A contour line<span> or isoline </span>connects points<span> on a map that are of </span>equal<span> value. Examples of contour </span>lines<span> or isolines are isobars (pressure) and isotherms (</span>temperature<span>). Perhaps the prototypical example of a contour </span>line<span> is that which </span>connects points of equal<span> elevation (that is, height above sea level).</span>

The correct option is renewable resources make cleaner energy.
Renewable energy, often known as clean energy, comes from naturally regenerated sources or processes. Sunlight and wind, for example, continue to shine and blow, even if their availability is dependent on time and weather.
Renewable energy is energy generated from naturally replenished sources such as the sun and wind. Renewable energy may be used to generate electricity, heat and cool buildings, and power vehicles.
A renewable resource is one that can regenerate fast and is replaceable, whereas a nonrenewable resource is one that cannot be renewed by natural resources.
