Answer:
3
Step-by-step explanation:
First, multiply the bread cost 2.70 by 2, getting you 5.40.
Next, add 11 for the cost of the caketo 5.40 getting you 16.40
Subtract 16.40 from 20 to get how much money you get for the cookies, getting you 3.60
Divide 3.60 by 3 to find how much money each boy gets, getting you 1.20
Divide 1.20 by .40 to get the number of cookies each boy gets, getting you 3
Volume of cone canbe calculated using the following rule:
volume of cone = (1/3) x pi x (radius)^2 x height
from the givens:
pi = 22/7
I'll assume that the 10 cm refers to the height
radius = 16/2 = 8 cm
substitute in the equation to get the volume as follows:
volume=(1/3) x (22/7) x (8x10^-2)^2 x (10x10^-2)
= 6.7 x 10^-4 m^3
Adding square any number of a square root will result in an irrational number
