Answer:
56844.9 units squared
Step-by-step explanation:
The surface area of a cone is denoted by:
, where r is the radius and l is the slant height. The slant height is basically the length from a point on the base circle to the top vertex of the cone.
Here, since our diameter is 50 and diameter is twice the radius, then our radius is r = 50/2 = 25.
To find the slant height, we have to use the Pythagorean Theorem:
, where h is the height
![l^2=25^2+50^2=625+2500=3125](https://tex.z-dn.net/?f=l%5E2%3D25%5E2%2B50%5E2%3D625%2B2500%3D3125)
![\sqrt{l^2} =\sqrt{3125}](https://tex.z-dn.net/?f=%5Csqrt%7Bl%5E2%7D%20%3D%5Csqrt%7B3125%7D)
![l=25\sqrt{5}](https://tex.z-dn.net/?f=l%3D25%5Csqrt%7B5%7D)
Now, plug these values of r and l into the first equation above:
![A=\pi r^2+\frac{1}{2} \pi r^2*l](https://tex.z-dn.net/?f=A%3D%5Cpi%20r%5E2%2B%5Cfrac%7B1%7D%7B2%7D%20%5Cpi%20r%5E2%2Al)
≈ 56844.9 units squared
Answer:
5x² + 7x + 7
Step-by-step explanation:
Subtract 3 from 10
3x+5x²-x+7+5x
Subtract x from 3x
5x² +2x+7+5x
Add 2x and 5x to get the 7x
