Asphere and a cylinder have the same radius and height. the volume of the cylinder is . amie found the volume of the sphere.

ANSWER

EXPLANATION

The volume of a cylinder is given by

The radius of the given cylinder is r=t.

The height of the cylinder is h=k.

The volume of the given cylinder is

The volume of a cone with the same base radius and height is

The correct answer is Option 2

1/3 πt²k

Step-by-step explanation:

points to remember

Volume of cone = 1/3 πr²h

Where r - Radius of cone and

h - Height of cone

To find the volume of given cone

Here radius of cone r = t and

Height of cone h = k

Therefore we can write,

volume of cone =  1/3 πr²h =  1/3 πt²k

Therefore the correct answer is option 2

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
