<span>Given:
formula for the slant height of a cone is I= s-π(pie)r^2 over π(pie)
where S is surface area of the cone
S(surface area) = 500π ft^2
r(radius) = 15 ft
Required:
l in m
Solution:
</span>I = (s - πr²) / π
I = (500π - π(15)²) / π
l = 275 ft (1m / 3.2808 ft)
l = 83.82 m
Answer:
Step-by-step explanation:
For any quadrilateral to be a parallelogram
i) either both the pairs of opposite sides must be equal
ii) Both the pairs of opposite sides must be parallel
iii) Opposite pairs of angles must be equal
iv) Diagonals must bisect each other.
v) A pair of opposite sides must be parallel and equal
Here we are already given that AB || CD
So either we should be given that AD || BC
or we must be given that AB = CD
Here it is given AB = CD as an option.
So Option A) or the first option is the right answer that AB ≅CD is needed to prove ABCD is a parallelogram.
Answer:
Step-by-step explanation:
The inverse of a quadratic function is not a function.
Answer:
x=9
Step-by-step explanation:
(x+3)/2=6
Multiply each side by 2
2*(x+3)/2=6*2
x+3 = 12
Subtract 3 from each side
x+3-3 = 12-3
x = 9
Answer:
I notice that they are equal.
Step-by-step explanation:
The slopes are the same when they are on the same line
