Question

What is the radius of a circle with a diameter of 45 miles?

Answer 1

Answer:

r = 22.5

Step-by-step explanation:

R = D/2 = 45/ 2 = 22.5

Answer 2

22.5mi

Just remember to divide the diameter by two to get the radius. If you were asked to find the radius instead of the diameter, you would simply divide 7 feet by 2 because the radius is one-half the measure of the diameter. The radius of the circle is 3.5 feet. You can also use the circumference and radius equation
