Answer:

I can't give you an exact answer because the graph is too blurry.

Step-by-step explanation:

however I can tell you how to answer it,

so all you need to do is take each point on the graph and add 2 to the y coordinate and add 5 to the x. you so this because it says up and to the right. hope this helps

This is just the area of a square so

a = s^2

a = (36)(36)

a = 1296 inches

But for the love of God pls review, this is the easiest formula of life

Find

saveliy_v [14]

Answer:

7 cm.

Step-by-step explanation:

Area of the 2 bases = total area - area of curved surface

= 408 - 100 = 308cm^2.

So the area of 1 base = 154 cm^2.

If radius of the base = r:

pi r^2 = 154

r^2 = 154/pi

r = sqrt (154/pi)

r = 7.0014 cm
