To answer the given question, substitute the values given to the equation,
S = π x sqrt(r² + h²)
155 m = π x sqrt (r² + (21 m)²))
r = 44.65 m
Therefore, the radius of the cone is approximately 44.65 m.
Answer:
0.08
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
You have to plug numbers into point slope formula (make sure to use a slope of -4/3 since its perpendicular) and then solve for y.
Answer:
Identify the slope, m. This can be done by calculating the slope between two known points of the line using the slope formula.
Find the y-intercept. This can be done by substituting the slope and the coordinates of a point (x, y) on the line in the slope-intercept formula and then solve for b.
Step-by-step explanation:
The general formula is y = mx +b.
m = slope.
b = y-intercept of the line
