Answers

Answer:

Radius is the distance from the center of the circle to the edge (if you were to cut just a slice of pizza)

diameter is directly in the middle from one end to the other (if you were to cut the pizza in half)

this means that the diameter is DOUBLE the radius

circumference is the length of the outside of the circle (so the length of the pizza crust)

this one is tricky because to find circumference you need to do  [tex]2\pi r[/tex] (r is the value of the radius)

so for problem 1 the radius is 3 cm (the line is equivalent to if you were trying to cut out one slice of pizza)

the diameter is DOUBLE the radius, so if you were to cut the pizza in half all the way it would be 6 cm

and the circumference ([tex]2\pi r[/tex]) is 2 * pi * 3 cm

because it says to round pi to 3.14, the circumference would be 18.84

lmk if this wasn't a good explanation or if you want help on the other problems too

Which are equivalent ratios to 2:3?
Check all that are true.

10:16

8:12

6:9

9:12

4:6

Answers

Answer:

8:12 6:9 4:6

Step-by-step explanation:

Divide each ratio by 2:3 and check if both numbers on either side of : are the same

For example:

8:12 divided by 2:3 = 4:4

Answer:

8:12, 6:9, and 4:6

Step-by-step explanation:

Equivalent ratios are any ratios that represent the same when they are simplified. All the ratios above simplify to 2:3. When the 8 and 12 of 8:12 are both divided by 4, the result is 2:3. When the 6 and 9 in 6:9 are both divided by 3, the result is 2:3. When the 4 and 6 in 4:6 are both divided by 2, the result is 2:3. The ratios 10:16 and 9:12 cannot be simplified to 2:3, and therefore are not correct answers.

Answer: congruent segment

Step-by-step explanation: it is the same segment on a different radius of a circle

The picture represents a final step used in constructing a congruent segment. The correct option is D.

What is congruency?

In geometry, two figures or objects are said to be congruent if their shapes and sizes match, or if one is the mirror image of the other. The meaning of congruency is that the two shapes are similar as well as equal in size.

In the given two figures the two angles are drawn. From the first angle, the measure of the second image is drawn. In the final step of the construction, the scale is used to draw the segment of the line of exact same length as the previous image. So it is a congruent segment of the line.

Therefore, the picture represents a final step used in constructing a congruent segment. The correct option is D.
