A fruit bowl is shaped like half of a sphere. The radius of the bowl is 15cm. what is the volume of the bowl

7065 cm

Step-by-step explanation:

Find the volume as the bowl was a whole sphere and then divide the volume found by two, to get the volume of half the sphere.

(4/3) * π*(r^3) ≈ 14130 cm

14130/2 ≈ 7065 cm

This is an approximated result using π = 3.14

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
