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>
An athletic director pays $90 for 12 sun visors for the
softball team. The rate per sun visor is equal to $90 / 12 sun visor = $ 7.5
per sun visor. So the athletic director should pay ($ 7.5 per sun visor)*(15
sun visor) = $ 112.5
