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:
A. technology can be used to overcome physical barriers and boundaries
Explanation:
The ability to dam water and use of improved transportation are clear proofs of how we can overcome physical barriers and boundaries.
- Dam water is an engineering revolution by which water can be made available all year round.
- Also, damage to the ecosystem caused by excess water is circumvented.
- Roads that are pliable are of huge important in breaching geographical imitations. A good transport system can make use of this connectivity.
- Air transportation has improved the ease of travel and reduced travel time greatly.
- Both dams and good transportation are clear engineering solutions to overcome limitations of nature.

<u>Answer:</u>
A method of transferring certain portions of the globe to a flat map is a projection is true.
<u>Explanation:
</u>
- In order to protrude down a part seen on the globe on a flat sheet of paper, it is mandatory to make certain adjustments in order to keep the angular and linear measurements intact and undisturbed.
- This process of taking down a part of the globe on a flat sheet of paper is referred to as 'projection'.
- For this projection to be accurate, it is primarily necessary to provide for the differences in angles and distances that may possibly occur depending on which part of the globe is to be projected.
Answer:
Explanation:
South Africa has a lovely, temperate climate with plenty of sunny, dry days. The main factors influencing conditions are altitude and the surrounding oceans. The east coast is on the Indian Ocean, which has a warm current. The west coast is on the Atlantic Ocean with a cold current.
