Which method is valid for proving that two circles are similar? a- Calculate the ratio of the diameter to the radius for each circle and show that they are equal.
b- Calculate the ratio of degrees to the circumference for each circle and show that they are equal.
c- Calculate the ratio of the área to the circumference for each circle and show that they are equal.
d- Calculate the ratio of the diameter to the circumference for each and show that they are equal.

Answers

Answer 1

Answer: First I'm going to go through the choices with you and evaluate
each one. Then after that, I'm going to hand you a secret that
I promise is going to knock your socks off.

a- Calculate the ratio of the diameter to the radius for each circle
and show that they are equal.
-- That won't tell you anything. The ratio of the diameter
to the radius of EVERY circle is 2 .

b- Calculate the ratio of degrees to the circumference for each circle
and show that they are equal.
-- That doesn't tell you anything. The circumference
of EVERY circle subtends a central angle of 360°.

c- Calculate the ratio of the área to the circumference for each circle
and show that they are equal.
-- That doesn't tell you anything. The ratio of the area
to the circumference of EVERY circle is (radius/2).
They're only equal if the circles are the same size.

d- Calculate the ratio of the diameter to the circumference for each circle
and show that they are equal.
-- That doesn't tell you anything. The ratio of the diameter
to the circumference of EVERY circle is 1/pi. If the ratio isn't
1/pi, then you're not looking at a circle.

None of these choices tells you whether the two circles are similar.
What are you going to do ? How can you tell ? ?

Here's the surprise I promised you.
Beware of flying socks:

All circles are similar to all other circles.

Good night.

Find the value of A in the equation 5/a+3=3/A-2

Answers

If you would like to find the value of a in the equation 5/a + 3 = 3/a - 2, you can do this using the following steps:

5/a + 3 = 3/a - 2 /*a
5 + 3a = 3 - 2a
3a + 2a = 3 - 5
5a = -2
a = -2/5

The correct result would be -2/5.

5+3a = 3-2a
So
5a = -2
a=-2/5=-0.4
