In this question, the volume of the cone is needed. The equation used to determine the volume of the cone is (1/3)π(r²)h
To solve for the volume, 
V = (1/3)π(3²)(10)
   = (1/3)(9)(10)π
   = (3)(10)π
   = 30π cm³
The correct answer is the first option which is 30π cm³.

Answer: A. 30π cm3

Step-by-step explanation:

The equation for cones

V = (1/3) π * r² * h

Plug in the numbers r = radius which is half of the diameter and h = height. Also leave out π because of the answer choices.

so... (1/3) * 3² * 10 = 30

30π

the point 3,2 lies on a circle.what is the exact length of the radius of this circle if the center is located at (-1,-4)
Crazy boy [7]
You can use the distance formula to solve this.

Distance Formula:
d = \sqrt{(X_2 -X_1)^2 + (Y_2 - Y_1)^2}

I am going to use point (3,2) as point 1 and (-1,-4) as point 2
Insert the points into the formula
d = \sqrt{(X_2 -X_1)^2 + (Y_2 - Y_1)^2}
d = \sqrt{((-1) - 3)^2 + ((-4) - 2)^2}
Solve:
d = \sqrt{((-1) - 3)^2 + ((-4) - 2)^2}
d = \sqrt{(-4)^2 + (-6)^2}
d = \sqrt{16 + 36}
d = \sqrt{52}
d = \sqrt{52} = \sqrt{4}\sqrt{13}
d = \sqrt{52} = 2 \sqrt{13}
d = 2 \sqrt{13}
radius = 2 \sqrt{13} = 7.2111

Y+23=59<br><br>solve for y i dont know if i have to add or subtract the 23 and 59
neonofarm [45]
When you move a number to the opposite side of the equation, in this occasion it will be 23- it changes to the opposite value. So us 23 is a positive value you can move it and change it to a negative. Or in other words suntract -23 from all sides of the equation, which will be equal to: 
y = 59 - 23
Y = 36
