Answer:
Volume of shaded portion = (600 - 36π) units³
Step-by-step explanation:
Volume of the shaded portion = Volume of pyramid - Volume of cone
Volume of pyramid = ⅓*l*w*h
Where,
l = length of base of pyramid = 15 units
w = width of base of pyramid = 10 units
h = height of pyramid = 12 units
Plug in the values to find the volume of the pyramid
Volume of pyramid = ⅓*15*10*12 = 5*10*12 = 600 units³
Volume of Cone = ⅓πr²h,
Where,
r = radius = ½ of diameter = ½ of 9 = 3 units
h = height = 12 units
Volume of Cone = ⅓*π*3²*12 = ⅓*π*9*12
= π*3*12 = 36π units³
Volume of shaded portion = (600 - 36π) units³
200 euros 300 euros
--------------- = -----------------------------
270 dollars x dollars
using cross products
200 * x = 270 * 300
divide each side by 200
x = 270 * 300/200
x =405 dollars
you don't list the choices but you would divide the total dollar amount by 5 to find out the number of bills there are so it should be something like :
total bills = x/5
That would be 30C4 - combinations of 4 from 30.
= 30*29*28*27
---------------- = 27,405 Answer
4 * 3 * 2 * 1
If your asking to multiply 9x5 then the anwser is 45.
