a globe has a diameter of 24 inches. a smaller globe has a diameter of 18 inches. What is the surface are to volume ratio of the smaller globe? round to the nearest hundredth.

1 pi: 3pi

Step-by-step explanation:

Step 1: Formula of surface area and volume of sphere

Surface area of sphere = 4 x pi x r^2

Volume of sphere = 4 x pi x r^3

3

Step 2: Apply values in the formula

r = radius

radius = diameter/2

r=18/2 = 9

S. A = 4 x pi x 9^2

S. A = 324pi

Volume = 4 x pi x 9^3

3

Volume = 972pi

Step 3 : Show in ratio

Surface area : Volume

324pi : 972pi

= 1 pi: 3pi
