Answer:
77.03 cm²
Step-by-step explanation:
The appropriate formulas are ...
CSA = Ch . . . . . curved surface area, C=circumference, h=height
where
C = πd
or
d = C/π
__
Here, we have ...
h = 2d = 2C/π
C = 11 cm
so the curved surface area is ...
CSA = (11 cm)(2(11 cm)/π) = 242/π cm² ≈ 77.03 cm²
V=(1/3)hpir^2
d/2=r
2.75/2=1.375
to make volume 4 times more
multiply height by 4 or multiply radius by 2
example
find current cup volume
V=(1/3)2.75pi1.375^2=2.2057291666666pi
if we times height by 4
3.5*4=14
V=(1/3)14pi1.375^2=8.822916666666666666pi
if we times radius by 2
1.375*2=5.5
V=(1/3)3.5pi5.5^2=8.822916666666666666pi
we can show it is 4 times by
8.822916666666666666pi/2.2057291666666pi= 3.99999 close enough
dimentions are
diameter of 2.75in and height of 11in or
diameter of 5.5in and height of 3.5 in
39.2 percent out of 112 that is 35%

You should first of all rewrite the equation in slope intercept form. You should get y=2/3x-2. The perpendicular slope is the opposite reciprocal, in this case -3/2. You will use this slope and the point to write your equation in point slope form and then clean this up to get it into slope intercept form. You should get y=-3/2x-6
