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: x = 10.3 ÷ 4
Step-by-step explanation: if we were to work this out forgetting about the equation it can be worked out by dividing the 10.3 by 4 to find the length of the pieces so, now to express it as an equation, we have to add x into our sum 4 × ? = 10.3 : 4x = 10.3. The answer for x would be x = 2.58.
Answer:
5120 cm^2
Step-by-step explanation:
Base area = (18 x 40)/2 = 360 cm^2
Base perimeter = 18 + 41 + 41 = 100 cm
LA = 100 x 44 = 4400 cm^2
surface area = 360 x 2 + 4400 = 5120 cm^2
Answer:
B. (-3, -17)
Step-by-step explanation:
Plotting them out on a graph, the other 3 points are able to be connected as a parallelogram. If you don't have graph paper at home, you can do an online search for "online graph paper" and use that. I personally find it very helpful to be able to see these kinds of things with my eyes.
