A cone has a volume of 5 cubic inches. What is the volume of a cylinder that the cone fits exactly inside of? (1 point) 15 in3
20 in3
25 in3
30 in3

15 in³

Step-by-step explanation:

For cone:

V = (1/3)πr²h

For cylinder:

V = πr²h

The formulas are the same except for the 1/3 fraction in the formula for the volume of a cone. Since the formula for the cylinder does not have the fraction 1/3, if a a cylinder and a cone have the same radius and height, then volume of the cylinder is 3 times greater than the volume of the cone.

5 cu in. * 3 = 15 in.³

15 in.³

it is x=-4

step-by-step explanation:

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
