Find the two points on segment AB that divide the segment into 3 congruent Parts if A has coordinates (0 0) and point B has coor

Elena L [17]

Answer:

(3, 2), (6, 4)

Step-by-step explanation:

Since one end (A) of the segment AB is at the origin, the required points will be 1/3 and 2/3 of the coordinates of B:

(1/3)(9, 6) = (3, 2)

(2/3)(9, 6) = (6, 4)

The radius of the cylinder is 3 inches and the height is 8 inches. Find the volume of the cylinder.

Dafna11 [192]

Answer:

1584/7 in² ≈ 226.3 in²

Step-by-step explanation:

Given,

Radius R = 3 in
Height H = 8 in
Volume V = ?

We know that,

Volume(Cylinder) = πr²h

Substitute values,

π(3²)8
9(8)π
72π

Taking π as 22/7

72*22/7
1584/7 ≈ 226.3 in²
