Eduardwww [97]

Answer:

2cm

Step-by-step explanation:

The volume of water displaced by the rod is

v = πr^2 h = π * 3^2 * 8 = 72π cm^3

The drop in water level is the rod volume divided by the cross-section area of the tin, or

72π/(π*6^2) = 2 cm

Some one explain please
Artist 52 [7]

Answer:

x=3/4y-6

Step-by-step explanation:

Solve for x

-4x+3y=24

Add -3y to both sides.

-4x+3y+-3y=24+-3y

-4x=-3y=+24

Then Divide both sides by -4

-4x/-4= -3y+24/-4

x=3/4y-6

a circle with the area 9 pi has a sector with a central angle of 60 degrees. what is the area of the sector?
mylen [45]

Answer:

The area of sector is 4.71 sq unites

Step-by-step explanation:

Step 1: Area of the sector = Area of the circle × (C/360) where C is the central angle.

Area of the sector = πr²(C/360) = 9π × 60/360

                           = 9 × 3.14 × 1/6

                           = 28.26/6 = 4.71 sq units
