A diameter spans from one end of (in this case, a circle) to the direct opposite end, going through the center-point. The radius, on the other hand, is half of a diameter, and spans only from the center-point to a point on the circle.

In this case:

1) Diameter = 18 km (given)

Radius = 18/2 = 9 km

2) Diameter = 1 x 2 = 2 m

Radius = 1 m (given)

3) Diameter = 17 x 2 = 34 cm

Radius = 17 cm (given)

4) Diameter = 50 mm (given)

Radius = 50/2 = 25 mm

John has a swimming pool, in which the center of the pool to the edge is 3 meters. What is the diameter? Simply multiply 3 with 2:

3 x 2 = 6 meters

6 meters is the diameter.

Radio signals travel at a rate of 3x10^8 meter per second. How many seconds would it take for a radio signal to travel from a sa

Our satellite is at a distance (from Earth) of $9.6 * 10^6$ meters. Since:

$speed = \frac{distance}{time}$

Solving for time:

$speed * time = \frac{distance}{time} * time$

The time's on the right cancel, so we are left with

$speed * time = distance$

We then divide both sides by speed:

$\frac{speed * time}{speed} = \frac{distance}{speed}$

Now the speed's on the left cancel, and we are left with:

$time = \frac{distance}{speed}$

Now we plug in our numbers for speed and distance:
