Circumference = pi *d
250 = pi * d
divide each side by pi
250/pi = d
pi is approximately 3.14
250/3.14 = d
79.62 = d
the diameter is approximately 79.62 ft
Answer:
40*
Step-by-step explanation:
the whole line FC would measure 180* so then 180-50 for AGC then AGB is congruent to EGD so 180-50-90---> 130-90---> 40* so angleBGC is 40 degrees
Answer:
(a) P = 2x + 2r + 2πr
(b) x = ½(P - 2r - 2πr)
(c) x = 123 feet
Step-by-step explanation:
See Attachment for sketch of the track
Solving for (a): Perimeter of the track
This is calculated by adding the perimeter of the rectangle to the 2 semicircles as follows.
P = Perimeter of Rectangle + Perimeter of 2 Semicircles
P = 2(x + r) + 2 * πr
[Where r is the radius of both semicircles]
Open bracket
P = 2x + 2r + 2πr
Solving for (b): Formula for x
P = 2x + 2r + 2πr
Make x the subject of formula
2x = P - 2r - 2πr
Divide both sides by 2
x = ½(P - 2r - 2πr)
Solving for (c): the value of x when r = 50 and P = 660
Substitute the given values in the formula in (b) above
x = ½(P - 2r - 2πr)
x = ½(660 - 2 * 50 - 2π * 50)
x = ½(660 - 100 - 100π)
x = ½(560 - 100π)
Take π as 3.14
x = ½(560 - 100 * 3.14)
x = ½(560 - 314)
x = ½ * 246
x = 123 feet
If you’re being bullied there’s a lot you can do. While different tactics work for different people, the first thing you should do is try to work it out yourself.
Depending on how bad the bullying is (and as long as you don’t feel at risk, scared or physically threatened) you might want to try and work it out yourself – as a first step.
The more empowered you are, and the more you can help yourself, the better chance you have to stop the bully.
If the bully doesn’t change their behavior, that’s when talking to someone else can be really helpful.
The bully wants you to react. Their goal is to take away your power, make you sad and scared. And if you show them you are not sad and scared, they will often lose interest and they cannot take away your power.
Remember they want to upset you constantly so you get angry. If you don’t get angry, the bully will lose their own power.
Remember that bullies are human - they eat, sleep and live just like you do. The only difference is that you are NOT a bully! Bullies act the way they do because they lack the attention or parental love and nurturing that you have. They are insecure and bully only to feel powerful.
Bullies look for a reaction from you and often lose interest if they aren't given the satisfaction of getting one.
Step-by-step explanation:
Volume of a cylinder is:
V = πr²h
V = (3.14) (4 in)² (5 in)
V = 251.2 in³
Volume of a cone is:
V = ⅓ πr²h
V = ⅓ (3.14) (4 in)² (15 in)
V = 251.2 in³
The volumes are equal.
