Sal knows the volume of a cylinder is 500 cubic units. he wants to create a cylinder with twice the volume. which variation of the original cylinder will have a volume of exactly 1,000 cubic units?
-use the same radius but double the height.
-use the same height but double the radius.
-double the radius and double the height.
-use the same height but quadruple the radius.

The answer is the first one i.e  use the same radius but double the height

Step-by-step explanation:

Given the volume of cylinder=500 cubic units

In order to make the volume 1000 cubic units

we have to double it

Now volume of a cylinder =

If we double the height the volume will be double of the original

In rest all the options the volume will get increased by a factor other than 2

Hence double the height and use the same radius

step-by-step explanation:

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
