Can someone answer these 2 questions.
the cross section of a sphere is shown. what is the area of the cross section ?
this cylinder is 8 inches tall and has a volume of 200π in³.
find the area of the cross section?

The cross section of sphere is circle

Area of cross section = 25 in²

Step-by-step explanation:

From the figure we can see a cylinder with height 8 inches and volume 200 π in³.

The cross section of the cylinder looks like a circle.

To find the area of cross section

Volume of cylinder = Cross section area * Height

200 = cross section area * 8

cross section area = 200/8

 = 25 in²

Area of cross section = 25 in²

dont think so

step-by-step explanation:

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
