There are two cones, the area of a cone is base x height divided by 3. in order to find the base, you would need the area of the circle which is π r^2. once you have that, multiple it by the height and divide by three. you will need to find both of the cone’s volumes so you would need to add the two volumes together to find the volume of the entire shape

If I'm adding mixed numbers so the fractional part is less than 1. How would I solve 9 5/10 + 6 3/10?

Crank

The answer would be 15 4/5. This is because 9 + 6 is 15, and 5/10 + 3/10 is 8/10. We can add these two fractions together because they have the same denominator. So it would be 15 8/10, and 8/10 simplified would be 4/5(because i divided 8 and 10 by the same number until they can't be divided by a whole number anymore). So the answer would be 15 4/5, I hope this helped :)

Answer:

$5\sqrt{18}-\sqrt{32} \\=5 \sqrt{3 \times 3 \times 2} - \sqrt{2 \times 2 \times 2 \times 2 \times 2} \\ = 5 \times 3 \times \sqrt{2} - 2 \times 2 \times \sqrt{2} \\ = 15 \sqrt{2} - 4 \sqrt{2} \\ = \boxed{11 \sqrt{2} }$

<h3>11√2 is the right answer.</h3>
