18-6=12
2/3=0.66
12/0.66=18.1
18 is the answer
You would have to change it into an improper fraction which you would just subtract 14 from the numerator
The surface area of a cylinder is given by:
A = 2 * pi * r * (r + h)
Where,
r: radio
h: height
Substituting values:
A = 2 * pi * 2 * (2 + 6)
Rewriting:
A = 2 * pi * 2 * (8)
A = 32pi square units
Answer:
A = 32pi square units
The area of a triangle is A= 1/2bh. Plugging in the values you know, 30= 1/2*12*h.
Solving for h,
30= 1/2*12*h
30= 6h
h=5
The height of the triangle is 5 units.
We can use the points (1, 2) and (3, -4) to solve.
Slope formula: y2-y1/x2-x1
= -4-2/3-1
= -6/2
= -3
Hope This helped! Good Luck!
