Answer: 42650
Step-by-step explanation:
The tens place is behind the ones place.
The number in the tens place in 42653 is 5.
So to round to the nearest tens you have to change three to 0 because if the number in the ones place is 5 or more, then the number in the tens place would be 1 higher than it used to be while the number in the ones place turns to 0.
However if the number in the ones place is less than 5, then that's the only thing that changes, the ones place would change into a '0.'
Hope that helped!
Answer:
Step-by-step explanation:
1. Set up the integral.
The equation for the circle is
x² + y² = 9
The bottom corners of the square are at
The length (a) of a side is
and the area (A) of the square cross-section is
A = a² = 4(9 - x²)
The volume (V) of the solid is
2. Solve the integral
![\displaystyle \int_{-3}^{3} {4(9 - x^{2})} dx = 4\begin{bmatrix}9x - \frac{1}{3}x^{3}\end{bmatrix}_{-3}^{3}= 4[(27 - 9) - (-27 +9)] = 4[18 - (-18)]\\= 4[18 + 18] = 4 \times36 = \mathbf{144}\\\\\text{The volume of the solid is $\large \boxed{\mathbf{144}}$}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Cint_%7B-3%7D%5E%7B3%7D%20%7B4%289%20-%20x%5E%7B2%7D%29%7D%20dx%20%3D%204%5Cbegin%7Bbmatrix%7D9x%20-%20%5Cfrac%7B1%7D%7B3%7Dx%5E%7B3%7D%5Cend%7Bbmatrix%7D_%7B-3%7D%5E%7B3%7D%3D%204%5B%2827%20-%209%29%20-%20%28-27%20%2B9%29%5D%20%3D%204%5B18%20-%20%28-18%29%5D%5C%5C%3D%204%5B18%20%2B%2018%5D%20%3D%204%20%5Ctimes36%20%3D%20%5Cmathbf%7B144%7D%5C%5C%5C%5C%5Ctext%7BThe%20volume%20of%20the%20solid%20is%20%24%5Clarge%20%5Cboxed%7B%5Cmathbf%7B144%7D%7D%24%7D)
I think its 90 so yeah um pick that
