Formula for the surface area of a sphere: SA = 4·π·r2

Formula for the volume of a sphere: V = (4/3)·π·r3

Surface area to volume ratio: ( 4·π·r2 ) / ( (4/3)·π·r3 ) = 3 / r

Radius = 5 ---> 3/5

The perimeter of a rectangle is 56 inches. The length is 4 more than 3 times the width. What are the dimensions of the rectangle

VashaNatasha [74]

Let the length be x and the width be y, then
2x + 2y = 56
x + y = 28 . . . (1)
x = 4 + 3y . . . (2)

Putting (2) into (1) gives
4 + 3y + y = 28
4y = 28 - 4 = 24
y = 24/4 = 6
x = 4 + 3(6) = 4 + 18 = 22

Therefore, length is 22 inches and width is 6 inches.
