Answer:
x = 14
Step-by-step explanation:
Since the triangles are similar then corresponding sides are in proportion, that is
=
( cross- multiply )
12(x - 4) = 120 ( divide both sides by 12 )
x - 4 = 10 ( add 4 to both sides )
x = 14

Hello from MrBillDoesMath
Answer:
See below for steps.
Discussion:
As I understand the problem statement we have a cylinder of height h and radius r. The volume of the cylinder is given by the formaul:
V = (pi * r^2) h
Divide both sides by (pi * r^2):
V\ (pi * r^2)) = ( (pi * r^2) * h ) \ ((pi * r^2) =>
V\ (pi * r^2) = 1 * h = h as (pi * r^2) \ (pi * r^2))
Therefore, h = V\ (pi * r^2)
Thank you,
Mr. B
Answer:
sqrt(A/pi), -sqrt(A/pi)
Step-by-step explanation:
A=pi*r^2
r^2=A/pi
r=sqrt(A/pi), -sqrt(A/pi)
Answer:
75
Step-by-step explanation:
(71+89+100+x)/3=83.75
(83.75*4)
335-100-89-71=75
