Question

Please answer correctly

Answer 1

Answer:

v = π S³ / 4

Step-by-step explanation:

r = cylinder's radius

A = cylinder base area

h = cylinder's height  

v = cylinder's volume

r = S / 2

h = S

Cylinder base area

Formula:

A = r²π

A = (S / 2)²π

A = (S² / 4)π

A = π S² / 4

Cylinder's volume

Formula:

v = Ah

v = (π S² / 4)S

v = π S³ / 4

Answer 2

Answer:

A.v=п*1/4*S^3

Step-by-step explanation:

the formula for the volume of a cylinder is v=п*r^2*h. here r=d/2=S/2 so r^2=S^2/4. h is the same lenght as the side of the cube so h=s. and then you just have to substitute r and s in the formula
