Answer:
![2261.9cm^{2}](https://tex.z-dn.net/?f=2261.9cm%5E%7B2%7D)
Step-by-step explanation:
Total Surface Area of Cylinder = ![2\pi rh+2\pi r^{2}](https://tex.z-dn.net/?f=2%5Cpi%20rh%2B2%5Cpi%20r%5E%7B2%7D)
Note: Do not get tricked by the 24cm (taking 24cm as the radius), that is the diameter.
To find r, radius = ![\frac{1}{2} d](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%20d)
=![\frac{1}{2} (24)\\](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%20%2824%29%5C%5C)
= 12cm
Now we know r = 12cm, h = 18cm
Now we substitute r and h into the formula to find the total surface area.
Total Surface Area of Cylinder = ![2\pi (12)(18)+2\pi (12)^{2} \\=432\pi +288\pi \\=720\pi cm^{2} \\=2261.9cm^{2}](https://tex.z-dn.net/?f=2%5Cpi%20%2812%29%2818%29%2B2%5Cpi%20%2812%29%5E%7B2%7D%20%5C%5C%3D432%5Cpi%20%2B288%5Cpi%20%5C%5C%3D720%5Cpi%20cm%5E%7B2%7D%20%5C%5C%3D2261.9cm%5E%7B2%7D)
Answer:
25
Step-by-step explanation:
Answer:
He is incorrect
Step-by-step explanation:
In 1.967, the hundredth is greater than 5. That means you'd round up! So, the correct answer would be 2.
(I tried my best to explain)
The formula is V=Bh
You'd get the base (it's a circle so you'd have to do A=pie*radius square)
Once you find the base, you mutliply it by the height
