How do you work out the length of radius and diameter of these two circles?
bogdanovich [222]
So for the first one what you did was wrong as in wrong formula.
Radius is 5cm as it is given and diameter is double the radius which is 10.
So r=5
And D=10.

For the second one the diameter is 16cm as it is given and radius is half the diameter,so half of 16 is 8cm right?
So r=8
And D=16

-5/7 is greater than -4/5
White raven [17]

Answer:

Yes.

Step-by-step explanation:

Forget about the negative sign for now.

Just compare 5/7 and 4/5 first.

Find the common denominator so it's easy to determine which one is bigger/larger.

5/7=25/35 and 4/5=28/35

From here, you can tell which one is bigger/larger, right?

Definitely, 25/35<28/35.

5/7<4/5, but don't forget the negative sign.

It's -5/7 compared to -4/5, so the answer is yes, -5/7>-4/5.
