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:
Around the world the most significant restriction on access to potable water is money. While access to raw water sources, clean or otherwise, is important, the purification process itself is expensive. Once water has been rendered potable, it is important that it be delivered without reintroducing contamination.
Answer:
35. The sum of two numbers is greater then either number = <em>TRUE</em>
<em></em>
36. The product of two positive numbers is greater than either number = TRUE
37. The difference between two integers is less than either integer = TRUE but only of positive integers.
Explanation:
35.
Let's say we have 2+3. That equals 5, which is higher then both 2 and 3 ( ofc ).
36.
Also true, you can use the same formula above to see it.
37.
Two integer's difference is less than either integer, but only if your using positive integers
