So you are using Volume...
V=1/3(pi)r^2h
as you go thu this equation
15 x 15 =225
12 x12= 144
225-144= 81
81/9=9
which your piece would be 1/3 pi r^2h answer is 1356.48
and you round it to the nearest tenth. So
( 1356.5) is ur answer...... So (B)
Answer:
u take the 3.0 and then x it by 3 that should be the answer
Step-by-step explanation:
You can do this 2 ways, one is knowing the special right triangles called triplets. An example of a triplet would be 3-4-5 where the largest value is the hypotenuse. In this example, the other 2 sides are 3 and 4 and the missing side is the hypotenuse, so using the knowledge of triplets, we can find that the hypotenuse is 5.
algebraically, we can use the Pythagorean theorem; a^2+b^2=c^2 where a and b are the opposite and adjacent and where c is the hypotenuse. We can then substitute in the values to get : 3^2 + 4^2 = c^2. When simplified, we get 9+16=c^2. Simplify further, and get 25=c^2. Now we Square root both sides to solve for C. Finally, we get C=5. Your missing side is 5.
Answer:
c=9
Step-by-step explanation:
it’s because from the angles, you can see that this is an isosceles triangle, there the two sides have to be the same.
This depends as to whether you are just multiplying the square root by 3, or are doing a cube root function. In a cube root, the 3 would be located just at the bent part of the square root symbol, usually in a smaller font. If one just wanted to multiply a square root by 3, it does not matter whether or not the 3 comes before or after the root.
A cube root is equal to a value to the power of (1/3).
I hope this helps
