vol. \: of \: cone  =  \frac{1}{3} \pi \times r ^{2}  \times h

r = radius

h = height of cone

radius = 5.5÷2

= 2.75

vol. of mold = 1/3π × (2.75)^2 × 15

= 118.79 (5sf)

= 118.8 (nearest tenth)

Answer:

118.8 cubic inches

Step-by-step explanation:

volume of a cone is

vol \:  =  \frac{1}{3}  \times \pi  \times   \frac{ {d}^{2} }{4}   \times h

where d is base diameter and

h is cone height.

hence

vol \:  =  \frac{1}{3}  \times \pi \times  \frac{ {5.5}^{2} }{4}  \times 15 \\  = \pi \times \frac{30.25}{4}  \times 5 \\  = 118.8 \: cu \: in

Answer:

h = -t+20

After 8 hours the candle will be 12 inches

Step-by-step explanation:

We have 2 points (time, inches)

 (3,17)  and (5,15)

We can find the slope

m = (y2-y1)/(x2-x1)

   = (15-17)/(5-3)

   = -2/2

   = -1

We can use point slope form

y-y1 = m(x-x1)

Replace y with h and x with t

h-17 = -1 (t-3)

Distribute

h-17 = -t+3

Add 17 to each side

h-17+17 = -t+3+17

h = -t+20

And an electronics warehouse ships TVs and DVD players to retailers all throughout the United States. The weight of three televi
vodomira [7]
X= weight of TV
y= weight of CD

3x+5y= 62.5
3x+ 2y= 52
You can either solve for a variable, or eliminate a variable by subtracting the second equation from the first:

3x + 5y = 62.5
-(3x+2y = 52)
0 + 3y = 10.5, so y = 10.5/3 or 3.5.

Now plug y= 3.5 back into any equation to get x:

3x + 5(3.5) = 62.5
3x + 17.5 = 62.5
3x = 45
x = 15
Always check work. Both equations should be true for x=15, y= 3.5

Find the distance between the following coordinates: I(-a,b), J(a,b)
olchik [2.2K]

Answer:

2a

Step-by-step explanation:

using distance formula:

√(x₂-x₁)² + (y₂-y₁)²

putting values,

√{a-(a)}² + {b-b}² = √ {a+a}² + 0²

= √(2a)² = √4a² = 2a

Hope this helps:)
