Find the volume of the cone-
1 answer:
Answer:
12.6ft³
Step-by-step explanation:
Hey There!
So the first thing we need to do is find the formula for volume of a cone
r = radius
h = hypotenuse
Now all we have to do is plug in the hypotenuse and the radius
2²=4
4xπ=12.5663706144
And now we just round to the nearest tenth
so we can conclude that the volume of the cone is 12.6ft³

Yeah C should be the correct answer
Given:
students going to the game = 56
students in each van = 7
number of vans used = unknown; x
The number sentence that can be used to find out how many vans are needed to take the students to the game is:
7 * x = 56
x = 56/7
x = 8 vans needed.
Step-by-step explanation:
=(x+2)(x+6)
=x²+6x+2x+12
=x²+8x+12

Answer:
45
Step-by-step explanation:
Let the first term be a and the common difference be d.
So -18=4a+6d and -9=6a+15d. Solving this we get a=-9 and d=3.
So the sum of first 10 terms is 5*(2*(-9)+9*(3))=45
