Answer:perpendicular bisector theorem
Step-by-step explanation:
They cancel out each other
Imagine if you were multiplying
-2 * -3
you would get 6
if you did
-2 * 3
you would get -6 because there isn't another - to cancel it out
I learned it that when you have a negative before a negative, put parenthesis around the second number with the negative, so it looks like this
-(-2)
if you look at the -(- it looks like a plus sign
that probably doesn't make much sense but we cancelling it out is just a rule, we don't really know why we do it
Answer:
Diameter of the can = 18 Cm
Step-by-step explanation:
Given:
Curved surface of cylindrical can = 162
Height of cylindrical can = 9 Cm
Find:
Diameter of the can = ?
Computation:
Curved surface of cylindrical can = 2rh
Diameter of the can = 2×r
Diameter of the can = 2×9 Cm
Diameter of the can = 18 Cm
Think it's 400
7/8 x 3200= 3200/8= 400 400x 7 =2800
3200 - 2800= 400
so 1/8 of 3200 = 400
