<em>Find Slope:</em>
y = -x + 3
slope = -1
Perpendicular slope = 1
<em>Sub Slope into Equation </em>
y = mx + c
Found that m = 1 (slope = 1)
y = x + c
<em>Find C</em>
At (-1,3)
3 = (-1) + c
c = 3 + 1
c = 4
<em>Sub C into the equation </em>
y = x + 4
Answer:
Step-by-step explanation:
The body of the Cylinder.
Formula
Area of the body = circumference * length
circumference = 2*pi * r
r = 6 m
Circumference = 2 * 3.14 * 6
Circumference = 12 * pi
Area of body = 12*pi * length
area of body = 12*9 * pi
Area of body = 108* pi
Two ends
The diagram is not complete enough to know whether or not there are 2 ends or one. I'll assume 2.
Area = 2 * pi r^2 For both
Area = 2 * pi * 6^2
Area = 72 pi
Total Area
Total area = 72 pi +108 pi
Total area = 180 pi
Total Area = 180 * 3.14
Total Area = 565.2

Answer:
Commutative property of multiplication
Step-by-step explanation:
Properties of Multiplication:
Commutative:
Multiplying two or more factors in a different order.
ex: 2 x 4 x 5 = 2 x 5 x 4
Associative:
Multiplying factors in parenthesis with different grouping. usually to make the problem simpler.
ex: (13 x 4) x 25 = 13 x (4 x 25)
Distributive:
Distributing a multiplicand to factors in parenthesis.
ex: 2(4 - 1) = 2(4) - 2(1)
ex: 2(8+7) = 2(8) + 2(7)
