Answer:
Step-by-step explanation:
Since the pile of sand is conical, we would apply the formula for determining the volume of a cone which is expressed as
Volume = 1/3 × πr²h
Where
r represents the radius of the cone.
h represents the vertical height of the cone.
π is a constant whose value is 3.14
From the information given,
Diameter = 18 feet
Radius = Diameter/2 = 18/2
Radius = 9 feet
Height = 10 feet
Therefore,
Volume = 1/3 × 3.14 × 9² × 10
Volume = 1/3 × 3.14 × 81 × 10
Volume = 847.8 ft³
Answer: A. 70.50
Step-by-step explanation:
So 350*0.11 is 38.50. Add the $32.00 and you get $70.50
Answer: D
Step-by-step explanation:
Isosceles Triangle has 3 sides, that has 2 sides of equal length.
Equilateral Triangle has 3 sides, that has 3 sides all of equal length.
If you have heard of the Hypotenuse, it has 3 sides of all different lengths maybe that's what this? But, the answer would indeed be D. Form Neither an equilateral nor an isosceles triangle.
Happy Mathing!!
A=future amount
P=present amount
r=rate in decimal
n=number of times per year compounded
t=time in years
how many years to double
basically
A=2P at t=?
so we can simplify and ignore the pricipal given and do
r=5.5%=0.055
n=1
t=t
take the ln of both sides
divide both sides by ln1.055
use calculator to aproximate
12.9462=t
about 12.9 years
