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.

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380
