Question

The radius of a circle is 5 units. What is the diameter of the circle?

Answer 1

Answer: 10 units

Explanation: The radius is 5 units. since it is asking for the diameter, if it is half of half a circle, the unit is the radius and the diameter is the same as the radius but doubled

EXAMPLE. half of half a circle is 5cm. The radius would be 5cm and the diameter would be 10cm. 5+5=10=the diameter

Radius 5cm

Diameter 10cm

THE ANSWER IS 10 UNITS

Answer 2

10

just multiply the radius by 2 because its half

hope this helps :)
