Hey there! I'm happy to help!
To find the volume of a cone, you take the area of the base, multiply it by the height and divide it by three.
We see that the radius of our base is three. To find the area of the base, we will square the radius and multiply it by 3.14 (formula for area of circle).
3²=9
9×3.14= 28.26
We multiply it by the height.
28.26(2)=56.52
We divide it by three.
56.52/3=18.84
Therefore, the area is 18.84 units cubed.
Now you can find the volume of cones! I hope that this helps! Have a wonderful day!
Answer:
Power = current * voltage
Power = 12 * 110
Power = 1,320 watts
Step-by-step explanation:
Substitute x for 3 & y for -2
22 - 2(-2) = 26
3(2) + 2(-2) = 2
-2, 0, 2, and 4 are the x values. To find y, we must substitute x for each of these values in y = -3/2x + 2.
-3/2 times -2 = 3. 3 + 2 = 5. The y value that goes with -2 in the table is 5.
-3/2 times 0 = 0. 0 + 2 = 2. The y value that goes with 0 is 2.
-3/2 times 2 = -3. -3 + 2 = -1. The y value that goes with 2 is -1.
-3/2 times 4 = -6. -6 + 2 = -4. The y value that goes with 4 is -4.
So, the table/coordinates are:
(-2, 5)
(0, 2)
(2, -1)
(4, -4)
I hope this makes the process clear.
