The answer is 35 degrees. x= 35 degrees
Answer:
the lateral surface area of a cone is 35π inches^2
Step-by-step explanation:
Given that
The diameter is 7 inches
And, the slant height is 10 inches
We need to find out the lateral surface area of the cone
We know that
The Lateral surface area of the cone is
= πrl
= π × 7.5 ÷ 2 × 10
= 35π inches^2
Hence, the lateral surface area of a cone is 35π inches^2
Answer:
y = x - 2
Step-by-step explanation:
Given coordinate:
( − 6 , − 1 )
Equation of the given line is 6x− y = 7
Unknown:
Equation of the line that passes through the point and is perpendicular = ?
Solution:
A perpendicular line will have a slope that is of negative inverse to the one given;
6x - y = 7
-y = -6x + 7
y = 6x - 7
According to y= mx + c
y and x are the coordinates
m is the slope
c is the y-intercept
Therefore, the slope of the line = 6
Perpendicular to this =
The new line will be;
Let find the intercept;
-1 = x (-6) + c
-1 = 1 + c
c = -2
The new line is;
y = x - 2
