<u>Step 1: Define</u>
y² - 7y + 6
y = -3
<u>Step 2: Evaluate</u>
- Substitute in <em>y</em>: (-3)² - 7(-3) + 6
- Exponent: 9 - 7(-3) + 6
- Multiply: 9 + 21 + 6
- Add: 30 + 6
- Add: 36
Answer:
radius is 4 height is 10 volume is 167.55
Step-by-step explanation:
Cylinder: First you need to find the radius. To do that, you need to divide the diameter by 2
Then, you multiply it by itself
After that, you multiply it by the height
And finally multiply it by pi
Cone: First, you need to find the radius dividing the diameter by 2
Then, multiply it by itself
After that, divide the height by 3
Finally, multiply the radius times the height and then multiply it by pi
The answer to the cylinder is 251.2 and the answer to the cone is 251.2
The processes are the following:
Cylinder
D:8
R:4
V:π4^2*5
V:π16*5
V:80π
V:251.2
Cone
D:8
R:4
V:π4^2 15/3
V:π16*5
V:80π
V:251.2
