The measure of the angle that represents 
of a circle is 45°
Step-by-step explanation:
Let us revise some important rules in a circle of radius r
- The length of the circle is 2πr
- The measure of the circle is 360°
∵ An angle represent of a circle
∵ The measure of the circle is 360°
- The measure of the angle is of the measure of the circle
∴ The measure of the angle = × 360°
∴ The measure of the angle = 45°
The measure of the angle that represents of a circle is 45°

Yes he is correct because -18/3 would turn into -6 a whole number
Answer:yes 5,5
Step-by-step explanation:
A transformation is rigid if the original shape remains the same shape and size after the transformation.
Flipping a pancake:
After it is flipped, the pancake should stay the same size and shape, so it is a rigid motion and it is a rotation.
Deflating an air mattress:
Deflating a mattress changes its size, so the transformation is not rigid. This is called a dilation.
Moving a clock's minute hand:
Moving the minute hand does not change the hand's size or shape so the transformation is rigid. This transformation is a combination of a translation and a rotation. The translation is what moves the hand around the center of the clock, and the rotation is what changes the direction of the hand.
Enlarging a photo:
Enlarging a photo changes the photo's size, so this transformation is not rigid. This is called dilation.
Putting a golf ball:
Putting does not change the size or shape of a golf ball, so this transformation is rigid. Putting a golf ball both rotates and moves the ball, so the transformation is rotation and translation.
Looking in a car's rear view mirror:
Assuming the car is moving relative to something behind it(because otherwise there would be no transformation), As things come closer to the back of the car, they would appear larger in the mirror, and as things move away from the back of the car, they would appear smaller in the mirror. Because the size changes when looking at the mirror, this is not a rigid transformation and is called dilation.
