Hey there! :)
The formula for finding volume of a cone = (π · r² · h) ÷ 3
π = 3
<em>Remember that d is 2x the r. To find r when given d, divide by 2</em>
d = 3
3 ÷ 2 = 1.5
h = 8
3 × 1.5 × 8 = 36
36 ÷ 3 = 12
The volume is 12 in³
Hope this helps :)
Yes you are correct! This equation will make a parabola. The width when the arch is at ground level would be the x-intercepts, or zeros, of the parabola.
The vertex point is (0,12)
the axis of symmetry is 0
The zeros are (-4,0) and (4,0)
using the zeros take away the negative because something cant be negative feet wide and add the numbers together (4+4)
Your answer is 8
i attached the graph
Hope this helps you!
P.S. Can i get brainliest? :)
Answer: $32.20 for the total bill & $4.20 for a 15% tip.
Step-by-step explanation: To find a 15% tip on a $28 dinner, all you have to do is simply multiply $28 by 15%. First, convert 15% to a decimal. 15 divided by 10 = 0.15.
Next, multiply 28 x 0.15 to find the tip. 28 x 0.15 = 4.20
So a 15% tip on a $28 dinner is $4.20
To find the total of the bill add $4.20 to $28, which gives you a total bill of $32.20.
