The volume of a cylinder is 32.25 cubic inches. If a cone has the same height and radius as the cylinder, what is its volume? A. 8.06 cu. in.
B. 10.75 cu. in.
C. 21.5 cu. in.
D. 32.25 cu. in.

B.   10.75 cu. in.

Step-by-step explanation:

Vol. of cylinder = πh = 32.25

If the cone has the same radius and height,

then the vol. of the cone = πh/3 = 32.25/3 = 10.75 cu. in.

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.
