Answer:
The volume is ![105.625\pi\ cm^{3}](https://tex.z-dn.net/?f=105.625%5Cpi%5C%20cm%5E%7B3%7D)
Step-by-step explanation:
we know that
The volume of a cylinder is equal to
![V=\pi r^{2}h](https://tex.z-dn.net/?f=V%3D%5Cpi%20r%5E%7B2%7Dh)
we have
![r=3.25\ cm](https://tex.z-dn.net/?f=r%3D3.25%5C%20cm)
![h=10\ cm](https://tex.z-dn.net/?f=h%3D10%5C%20cm)
substitute
![V=\pi (3.25)^{2}(10)=105.625\pi\ cm^{3}](https://tex.z-dn.net/?f=V%3D%5Cpi%20%283.25%29%5E%7B2%7D%2810%29%3D105.625%5Cpi%5C%20cm%5E%7B3%7D)
She is incorrect because we technically have the angle for G since it’s a right angle (90°) meaning we can solve this problem :) hope that’s correct
What does the shape look like?
Ok, so say you are calculating the surface area of the shape in the image below.
You would calculate the area of both shapes (the vertical box and the horizontal one), then subtract the area of the left face of the left rectangle (it is 10x20). That way, you are subtracting the area from the tall box. Make sure when you calculate the area of the short box that you don't include the left face (which is non-existent because it is attached to the tall box). If this is still really confusing (don't blame you if it is!!), let me know and I will walk through and example with you. Hope this helps!!
Answer:
45-12=33
Step-by-step explanation:
you subtract 45 by 12 and get 33
Answer:
143 square meters
Step-by-step explanation:
The surface has a width of 11 meters and a length of 13 meters.
13 x 11 = 143.
Is this correct?
