Answer:
4.013 units
Step-by-step explanation:
We know that the volume of a cone is given by the following equation:
v = pi / 3 * r ^ 2 * h
we need to know the height, therefore we solve for h:
h = 3 * v / (pi * r ^ 2)
replacing v = 105 and r = 5
h = 3 * 105 / (3.14 * 5 ^ 2)
h = 4.013
Which means that the height measures 4.013 units
Just do 300x1.4 because that gives you the extra 40% (the answer is £420 btws)
Answer:
Step-by-step explanation:
THe sides are the same length
11=x+5
x=6
Answer:
area: A = 8 m^2
Step-by-step explanation:
Area of a rectangle: A = ab
Answer:
y = 
- 8
Step-by-step explanation:
given slope m = 
point (5, -2) for (x1, y1)
equation for point slope form
y - y1 = m(x- x1)
y - (-2) = (x -5)
y + 2 = x - 6, simplify
y = - 8,
further you can multiply by 5 to get rid of fraction
5y = 6x - 40
