v = 17.06851cu.inches
when rounded the answer would be 20cu. inches
The formula for finding the volume of a cone is
1/3(hπr^2)
since we don't know the radius we can find it out through the equation of finding the circumference which is π x d =9.8inches
so the diameter is 9.8/π
which is 3.119437 inches
since the diameter is 2xradius so it would be
3.119437/2=1.559718
so now we can plug this into our equation

1/3(6.7x3.141592653x1.559718^2)
so that would be 17.06851cu.inches

Felipe's Coffee Shop makes a blend that is a mixture of two types of coffee. Type A costs Felipe $4.55 per lb. Type B costs $5.7
RUDIKE [14]

Answer:

Type A coffee in lbs = 97 lbs

Step-by-step explanation:

Type a = 4.55/lbs = x

type b = 5.70/lbs =  y

Total in lbs = 147lbs

total in sales = 726.50

First,

x + y = 147 lbs    -------------------equ 1

4.55x + 5.70y = lbs    ------------ equ 2

<em>Multiply equ 1 by 4.55</em>

4.55x + 4.55y = 668.85  -------------equ 3

4.55x + 5.70y = 726.50   ------------equ 4

<em>Subtracting equ 3 from equ 4</em>

1.15y = 57.65

y = 50

<em>Substituting y = 50 into equ 1</em>

x + 50 = 147

x = 97
