To solve this completion exercise, you must keep on mind the following information:

 - The formula for calculate the area of a sphere, is the following:

 Vsphere=4πr³/3

 Where Vsphere is the volume of the sphere and "r" is the radius of the sphere.

 - Therefore, if you multiply the radius by 3, or triple the radius, the surface area increase by a factor of 9 (3^2=9).

 The answer is: T<span>ripling the radius of a sphere increases the surface area by a factor of 9.</span>

A dolphin can swim up to 40 miles per hour.what is the speed in feet per hour?
zalisa [80]
In this question, the speed of the dolphin is already given, but the unit is different. The speed of the dolphin is given as 40 miles per hour and it has to be converted to feet per hour.
We already know that 1 mile = 5280 feet
Then
40 mile = 5280 * 40 feet
            = 211200 feet
So the speed in feet per hour will be 211200 feet per hour. I hope the procedure is clear enough for you to understand. You can always use this method for solving similar problems without requiring any help from outside.
