The diameter of a circle is four units. What is the radius of the circle?

the radius of the circle is 2 units.

Step-by-step explanation:

this is because the diameter is the length of the circle from one point of the circle, intersecting the center point of the circle to the other edge.

the radius is half of that. this is because the radius is the length from the center point of the circle to a point on the edge of the circle.

so if the diameter is 4 units, then the radius of the circle would be 4/2 = 2.

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

spinning a 1, 2, or 3. option d.

step-by-step explanation: when spinning a number graph up to 4, and aiming for any number less than 3, that automatically eliminates the number 4. now you have two numbers to spin on that are less than 3, but the number 3 is included in this question because it's no greater of an number than itself. i hope this you : )
