In order to determine the distance in between the given points, use the following formula:

d = √((x1 - x2)² + (y1 - y2)²)

where, for this case, (x1,y1) = (-1,3) and (x2,y2) = (3,5).

Replace the values of the parameters:

d = √((-1-3)²+(5-3)²)

d = √((-4)²+(2)²)

d = √(16+4)

d = √20

d = 4.47

Hence, the distance in between A and B is 4.47 units

Answer

a. The volume is multiplied by 4

b. The volume is doubled

Explanation

a. The volume of a cone with radius r and height h is $\pi r^2 h/3$ . If the radius is doubled, the new volume will be $\pi (2r)^2h/3$ , which is equal to $4\pi r^2h/3$ . This means that the volume is multiplied by 4.

b. The volume of a cone with radius r and height h is $\pi r^2 h/3$ . If the height is doubled, the new volume will be $\pi r^2(2h)/3$ , which is equal to $2\pi r^2 h/3$ . This means that the volume is multiplied by 2.
