Hi there! :)
Answer:

Use the formula V = 1/3(bh) to solve for the volume of the cone where b = πr² where π ≈ 3.14:
Find the area of the base:
b = π(7)²
b = 49π
b = 153.86 mm²
Find the volume:
V = 1/3(153.86 · 7)
V = 1/3(1077.02)
V = 359.006 ≈ 359.01 mm³.
Answer:
Step-by-step explanation:
Here the average rate of change would be
f(6) - f(1) 162 - (-8)
a. r. of c. = ----------- = ------------------ = 154/5 = 308/10 = 30.8 or 30 8/10
6-1 5 or 30 4/5
Answer: 22
Step-by-step explanation:
She sold two tubs of Oatmeal Raisins and it's 6 dollars a tub so we can do 6*2 or 6+6 (doesn't matter). We get $12. Then, she also sells 2 tubs of Peanut Butter, and since it's $5 a tub, then we do 5*2 or 5+5 to get 10. We add 12 and 10 (12+10) and get 22.
I'm not sure if this is right because you added $22, $24, $20, and $11 and I'm not sure what the purposes of those are.
So, we need to add.
45 + 30 = 85.
$0.85 is your answer.
Glad I could help, and good luck!

If m(slope)=3, you can start to set up the equation as y=3x+b.
Using y=3x+8, you can plug in the given point being (8,5).
y=5
x=8
5=(3*8)+b
5=24+b
b=-19
The equation would be y=3x-19
