Answer:
perpendicular slope =
Step-by-step explanation:
Calculate the slope m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (6, - 6) and (x₂, y₂ ) = (- 1, - 3)
m = =
= -
Given slope m then the slope of a perpendicular line is
= -
= -
=
Answer:
Step-by-step explanation:
Given:
The radius of a cylindrical gift box =
The height of the gift box is three times the radius.
Question asked:
What is the surface area of the cylinder ?
Solution:
The height of the gift box is three times the radius means,
Now, surface area of the cylinder =
Therefore, surface area of the cylinder is .
